Jennifer and Janna are trying to figure out how to control the mouse problem in their horse barn. They have tried several types of traps baited with peanut butter with no luck. The girls decide that the problem might not be the type of trap; it might be the type of food. What is the BEST question for the girls to use on their next experiment?

Answer:

the resistance force is mg cos(-)

Explanation:

The resistance force on an inclined plane is generated by a portion of the object's weight acting downward along the plane and the counteracting frictional force. It opposes your upward movement. The total force exerted walking up an incline is less than lifting the same weight vertically, which explains why it's easier to walk uphill than climb a ladder of the same height.

When you walk up an inclined plane, you encounter two forces due to gravity: a force acting perpendicular to the plane and a force acting parallel to the plane. The perpendicular force is typically equal in magnitude and opposite in direction to the normal force. The force acting parallel to the plane leads the object to accelerate down the incline. This is the resistance force you experience when moving up. It's composed of a part of the weight (W) inclined downward along the plane and the opposing frictional force (f). Specifically, if the incline is at an angle Θ, the resistance force, W_parallel, can be expressed as W_parallel = mg sin(Θ), where m is mass and g is the force of gravity, and the kinetic friction, f_k, can be expressed as: f_k = μ_k mg cos(Θ).

However, when walking, you work against the resistance to move forward, and hence, the net force is not zero. As a result, climbing an inclined plane is less strenuous than climbing directly upwards, though it demands work over a greater distance.

Explanation:

The Option that explains the process of radiation is :  ( C ) when heat gets transferred through electromagnetic waves that move through space

Radiation is the transfer of energy through space in the form of electromagnetic waves or as subatomic particles. Energies transferred during radiation move at the speed of light.

During conduction and convection heat gets transferred through objects that touch each other while during radiation the objects do not have to be in contact for energy to be transferred.

Answer:

-29.4 m/s

Explanation:

Given:

v₀ = 0 m/s

t = 3 s

a = -9.8 m/s²

Find: v

v = at + v₀

v = (-9.8 m/s²) (3 s) + (0 m/s)

v = -29.4 m/s

The final velocity of a ball dropped from rest for 3 seconds is -29.4 m/s.

Given the following information:

The ball is dropped from rest.

The acceleration due to gravity is g = -9.8 m/s².

The time the ball falls is t = 3 seconds.

Use the following formula to calculate the final velocity of the ball:

v = v_0 + g × t

where:

v is the final velocity of the ball

v_0 is the initial velocity of the ball (which is 0 in this case)

g is the acceleration due to gravity

t is the time

v = 0 + (-9.8 m/s²) × 3 seconds

v = -29.4 m/s

Therefore, the final velocity of the ball is -29.4 m/s.

The negative sign indicates that the velocity is downwards.

The speed of the car will be approximately 9.14 meters per second.

To find the speed of the car, we can use the Doppler effect equation for frequency shift:

Δf/f₀ = v/c

where:

Δf = frequency shift (638 Hz lower in this case)

f₀ = original frequency emitted by the speed gun (2.10x10¹⁰ Hz)

v = velocity of the car

c = speed of light in a vacuum (approximately 3.00x10⁸ m/s)

We need to rearrange the equation to solve for the velocity (v) of the car:

v = Δf/f₀ × c

Now, let's plug in the values:

Δf = 638 Hz

f₀ = 2.10x10¹⁰ Hz

c = 3.00x10⁸ m/s

v = 638 Hz / 2.10x10¹⁰ Hz × 3.00x10⁸ m/s

Calculate the value:

v ≈ 9.14 m/s

So, the speed of the car is approximately 9.14 meters per second.

To find the charge q1, set up equations for the electric fields created by each charge and solve them simultaneously. The value of q1 is -150 nC.

To find the charge q1, we need to consider the electric field created by each of the three charges separately. Since the total electric field at the origin is zero, the electric fields from charges Q, q1, and q2 must sum up to zero.

We can use the formula for the electric field due to a point charge, which is given by E = k * Q / r^2, where k is the electrostatic constant, Q is the charge, and r is the distance from the charge to the point of interest. By setting up equations for the electric fields from each charge and solving them simultaneously, we can find the value of q1.

After solving the equations, we find that the charge q1 is equal to -150 nC.

Final answer:

The amplitude of a wave is half the height from peak to trough, so a 2 m crest above still water has an amplitude of 1 m. A seagull bobbing every 2 seconds between 3 m apart crests experiences a wave velocity of 1.5 m/s. A boat hit by a 2 m high wave peak will change elevation by 2 m.

Explanation:

The question provided is related to the physics of waves, specifically their propagation, amplitude, frequency, and wavelength. When discussing a wave crest measuring 2 m above the still water mark, the amplitude of the wave is actually 1 m, as the amplitude corresponds to the maximum displacement from the equilibrium (still water level) to the peak of the wave, which would be half of the peak-to-trough height.

Therefore, if a wave's crest is 2 m above the still water mark, and assuming the trough is the same distance below, the amplitude is 1 m.

Similarly, for a seagull bobbing up and down on the water's surface, if it does so once every two seconds and the distance between two crests of the water wave is 3 m, the velocity of the wave would be 1.5 m/s (wavelength divided by the period: 3 m / 2 s = 1.5 m/s).

Regarding a boat that bobs up and down due to wave action, if the height of the wave is 2 m, the boat's height will change by 2 m when hit by the peak of the wave, considering the change from the equilibrium position to the peak.

The controversy over genetic differences in intelligence primarily relates to the misuse of genetic arguments for racial discrimination and the oversight of environmental influences on intelligence.

The study of genetic differences in intelligence has been controversial due to several factors. The primary concern arises from the historical use of genetic arguments to justify racial discrimination. These views, although scientifically refuted, have at times resurged, as in the case of 'The Bell Curve'. Notably, the controversy arises from interpretations that link genetics and race with intelligence without accounting for the significant influence of environmental variables. Additionally, research has shown a closing of IQ gaps with increased access to education, pointing to nurture's critical role in intelligence development. The persistence of the idea that intelligence could be predetermined by race without adequate consideration of environment and socioeconomic factors contributes to the ongoing debate.

Moreover, there is a recognition that intelligence is affected both by genetics and environment, with environmental influences shaping the manifestation of cognitive abilities. Twin studies show a genetic component to intelligence, but conflict theorists note that IQ tests can be biased and do not always offer a fair assessment of a person's intellectual capabilities, reinforcing the complex interplay of genetics, environment, and social factors in the development of intelligence.
