The hint in this problem is in the word "about" or approximately how many pounds.
So we could find the solution by estimation through rounding off.
We know that almonds cost about 3.50 per pound and a bag costs about $7.00.
Dividing 7 by 3.50 per pound, will give us $7 ÷ $3.50 = 2 pounds.
The answer is 2 pounds.
Answer:2 pounds of almonds are in the bag.
Explanation:
According to question ,pounds of almonds in $3.49 = 1 pound
Then pound of almond for $1 = [tex]\frac{1}{3.49} pounds[/tex]
Pounds of almond which cost $6.95:
[tex]\frac{1}{3.49}\times 6.95 pounds=1.9914 pounds\approx 2 pounds[/tex]
2 pounds of almonds are in the bag.
A 20-kg barrel is rolled up a 20-m ramp to the back of a truck whose floor is 5.0 m above the ground. What work is done in loading one barrel into the truck?
The angle of inclination is calculated using sin function,
sin θ = 5 m / 20 m = 0.25
θ = 14.4775°
The net force exerted is then calculated:
F net = m g sin θ = 20 * 9.8 * 0.25
F net = 49N
Work is product of net force and distance:
W = F net * d = 49 * 20
Work = 980 J

How is the acceleration of an object in uniform circular motion constant?
Uniform circular motion refers to the motion of an object moving in a circular path at a constant speed. Despite the constant speed, the object actually experiences constant acceleration due to its constant change in direction, which is coined as Centripetal Acceleration.
Explanation:Uniform circular motion is a principle in physics that describes the motion of an object traveling in a circular path at a constant speed. Although the speed is steady, the acceleration is not zero. This is because acceleration is not just the rate of change in speed, but also encompasses change in direction. Despite the constant speed in uniform circular motion, the direction of the object is always changing, hence creating acceleration.
Centripetally, the acceleration is directed towards the center of the circle along which the object is moving. The continuous change in direction results in a constant acceleration. This force that keeps the object moving along the circular path is known as the Centripetal Force. Therefore, even with constant speed, the continuous change in direction in a circular path results in constant acceleration, known as the Centripetal Acceleration.
As a concrete example, think about when you're driving and take a turn at a constant speed. You can feel yourself being pulled to the side, an effect of the centripetal acceleration.

Explain why the shortening velocity became slower as the load became heavier in this experiment. how well did the results compare with your prediction?
The shortening velocity is the rate at which a muscle shortens during a contraction. The force of a muscle contraction decreases with speed.
What is shortening velocity?The pace at which a muscle shortens while contracting to lift a load is referred to as the shortening velocity. Only with a light load may the shortening velocity be increased to its maximum. The shortening velocity is at its maximum when the load is light.
When lifting a heavy object, the muscle moves more slowly as it slows down as it lifts the object. Muscles must exert additional internal effort to distort their tissue and, in particular, to overcome the inertia brought on by their internal mass in order to do outward work. The contribution of a muscle's internal bulk to its mechanical output has, however, hardly ever been researched.

Sally made breakfast for the family on Saturday morning. She put some bread in the toaster. When the bread popped up, Sally grabbed the toast. "Ouch! That's hot!" Sally exclaimed. What was the SOURCE of the heat that made the bread hot?
The heat that made in a bread toaster is infrared radiation. The coils inside the toaster produce infrared radiation and thus produce enough heat energy to be hot.
What is toaster?A bread toaster is a device used for cooking bread and related food items. The bread pieces can be easily heated using a toaster. Inside a toaster sufficient heat energy is produced to cook the breads.
Generally electric toasters uses a nichrome wire which wrapped back and forth surrounding a sheet made of mica. The nichrome coil produce high electrical resistance to get hot. One of the advantage of this alloy is that, they does not oxidise as iron.
A toaster radiated much energy by consuming maximum amount of electrical energy with high power rate. Heat is produced by conducting electricity through non-magnetic alloy nichrome wires.
The radiating wire make the coils glow red and which indicates the coils have much heat energy to toast the breads. This heat energy make its sheet surroundings to be hot and that's why sally felt it too hot.

Calculate the minimum and maximum angular diameters of the sun, as seen from mars.
The angular diameter can be calculated by using the formula,
Angular diameter = 57.3 x physical diameter / distance.
The physical diameter of the sun = 1.4 x 10^6 km.
The minimum distance of Mars from Sun = 205 x 10^6 km
The minimum angular diameter of the Sun as seen from Mars is:
Angular diameter = 57.3 x physical diameter / distance = 57.3 x (1.4 x 10^6 km / 205 x 10^6 km) = 0.39 degrees.
The maximum distance of Mars from Sun = 249 x 10^6 km.
The maximum angular diameter of Sun as seen from Mars is,
Angular diameter = 57.3 x physical diameter / distance = 57.3 x (1.4 x 10^6 km / 249 x 10^6 km) = 0.32 degrees
To calculate the minimum and maximum angular diameters of the Sun as seen from Mars, use the small-angle formula using the angular diameter of the Sun and the distances to Mars and Earth.
Explanation:To calculate the minimum and maximum angular diameters of the Sun as seen from Mars, we need to use the small-angle formula. The angular diameter of the Sun is about 0.5°. Mars has an average distance of 227 million kilometers from the Sun, and Earth is about 1 AU from the Sun. Using the small-angle formula, we can relate the angular diameter, the linear diameter, and the distance:
linear diameter = distance x angular diameter
For the minimum angular diameter, we use the distance from Mars to the Sun:
minimum angular diameter = 227 million km x 0.5° / 1 AU
For the maximum angular diameter, we use the distance from Earth to the Sun:
maximum angular diameter = 1 AU x 0.5° / 1 AU
By performing the calculations, the minimum angular diameter of the Sun as seen from Mars is approximately 0.96° and the maximum angular diameter is also approximately 0.5°.

Is a charge indicated on the neutral atoms if yes where is it located?
Neutral atoms carry no charge because they have equally balanced numbers of positively charged protons and negatively charged electrons. If an atom becomes an ion, it either gained or lost electrons, which affects its overall charge resulting in either a positive or negative charge.
Explanation:In neutral atoms, the number of positively charged protons and negatively charged electrons are equal. This balance gives rise to the atom's overall neutral net charge. The charge in an atom is defined by the equation: Atomic Charge = number of protons - number of electrons. If an atom gains or loses electrons, it ceases to be neutral and becomes an ion.
For instance, an atom that gains electrons has a negative charge and is called an anion. An atom that loses electrons, on the other hand, has a positive charge and becomes a cation.
Should the balance be disturbed, for instance, if a neutral sodium atom loses an electron, it would form a cation with a 1+ charge. On the contrary, if a neutral oxygen atom acquires two electrons, it would form an anion with a 2- charge.

Christopher can paddle a canoe in still water at 8 km/h. how successful will he be at canoeing upstream (against the current) in a river that flows at 8 km/h?
Christopher will not make any progress upstream. From the point of view of his friends standing on the riverbank, he'll remain at one point, motionless except for his furious paddling motions.
Given data:
The speed of Christopher in still water is, v = 8 km/h.
The speed of river is, u = 8 km/h.
The upstream is the motion of any object (say boat) in a river, which is in the direction opposite to the direction of flow of stream or river. And the expression for the upstream as per the given problem is,
upstream = v - u
So, on substituting the values we get,
upstream = 8 - 8
upstream = 0 km /h.
Thus, we can conclude that Christopher will not make any progress upstream. From the point of view of his friends standing on the riverbank, he'll remain at one point, motionless except for his furious paddling motions.

Answers assuming the bag does not break, what will be its volume at the top of a mountain where the pressure is 453 mmhg and the temperature is 8.00 ∘c?
The question is about physics and refers to the ideal gas laws. From the data provided, we know that the volume of the bag at the top of the mountain will change due to a decrease in pressure and temperature. By using the ideal gas laws equations, we can find the final volume of the bag.
Explanation:The question is inquiring about the change in volume for a bag when the pressure and temperature change from the base of the mountain to the top. Here, we will use the ideal gas laws which state that volume is directly proportional to temperature and inversely proportional to pressure. Given that the initial pressure is 760mmHg and the final pressure is 453mmHg and that the temperature fell from an average room temperature of 25°C (or 298.15 K) to 8°C (or 281.15 K), we can use these principle to solve the question. Note that pressure is given in mmHg and needs to be converted to the same unit.
You can calculate the change in the bag's volume using the relationship between the initial and final state: V1/T1 = V2/T2 where V1 is the initial volume and V2 is the final volume. Considering the pressure changes, you could use another ideal gas law equation that defines the relationship between pressure and volume: P1V1=P2V2, where P1 and P2 are the initial and final pressures respectively.
By applying these formulas, you can calculate the change in volume of the bag. Have in mind that this is an approximation since real gases don't always behave as ideal gases, especially under extreme conditions.
