Answer:
[tex]P=180W[/tex]
Explanation:
Given:
h = 5m
mg =720N
To calculate the workdone using the formula
W = mgh
Where W is the workdone
"m" is the mass of the man
"h" is the distance covered
Weight of the man = mg = 720N
where "g" is the Acceleration due to gravity
"m" is the mass of the man
Substitute the value of "h" and "mg"
W = 720 × 5 = 3600J
To calculate the power
[tex]P=W/t[/tex]
Where W= 3600W
t = time taken = 20s
P = 3600/20
[tex]P=180W[/tex]

Which expression represents the volume, in cubic units, of
the composite figure?
O (52)(13) - 1 (52)(12)
07(52)(13) – 1 (52)(25)
(52)(13) + (52)(12)
T(52)(13) + (52)(25)
Answer:
C. π(5²)13 + 1/3π(5²)12 cubic units
Explanation:
The composite figure is made up of a cylinder and a cone.
The volume of the composite figure = volume of the cylinder + volume of the cone
For the CYLINDER:
Volume = πr²h
h = height of the cylinder = 13units
r = radius of the cylinder = 5units
Volume = π(5²)13 cubic units
For the CONE:
Volume of a cone = 1/3πr²h
height of the cone = 25-13 = 12units
Radius of the cone = radius of the cylinder = 5units
Volume = 1/3π(5²)12 cubic units
Volume of the composite figure will give: π(5²)13 + 1/3π(5²)12 cubic units

Earth is currently 150 million km away from the Sun. If Earth was 200 million km away from the Sun, it would no longer support life because -
1)the surface water would evaporate.
2)the temperature would be too cold.
3)the oxygen would leave the atmosphere.
4)there would be less exposure to solar wind.
The Earth is 150 million kilometers from the Sun right now. The temperature on Earth would be too frigid to support life if it were 200 million kilometers from the Sun.
What role does the Sun play in supporting life on Earth?It produces light and heat, also known as solar energy, which enables life on Earth to exist. Sunlight is required for plants to thrive.
Animals, including humans, rely on plants for food and oxygen. If the sun did not provide heat, the Earth would freeze.

Note: Use slash (/) to separate numerator and denominator.
sin C

tan c
sin C, cos C, and tan C are calculated using the sides of a right triangle, where C is the angle. With the given values (A=25, B=0, C=24), it appears there's a mistake because the hypotenuse can never be zero. Therefore, correctly identifying sin C, cos C, and tan C with these values is not possible.
Explanation:In trigonometry, sin C, cos C, and tan C represent specific ratios in a right triangle where C is the angle. Given a right triangle with C as one of the angles, we can use the sides to calculate these ratios.
The sides of the right triangle are described as follows:
A represents the opposite side of angle C
25 is the adjacent side of angle C
0 is the hypotenuse. However, in a right triangle, the hypotenuse should never be 0. It seems there's a mistake because we cannot have a hypotenuse of 0.
Unfortunately, with the given values, correct answers for sin C, cos C, and tan C cannot be determined.

Trevor watched as the barometer on his front porch showed a change in air pressure.
What happened as Trevor was watching the air pressure change?
Answer:
While watching the air pressure change, the change that occur within the barometer is that the barometer (if aneroid barometer) contains within it a partially evacuated (vaccumed) steel corrugated box. The top surface is held by a strong spring to stop it from collapsing.
If the air pressure changes, the surface moves up or down with a decrease or increase in air pressure respectively. This movement is transmitted and amplified by a connected system of jointed lever and chain that passes around a grooved wheel. This transmission is to a pointer that is deflected with these change and movements to give the reading on the scale. The scale is is often calibrated in millibars; higher pressure indicates a bad weather.

D. measure of the amount of air pressure on a
body of water
Answer: A. Measure the amount of water vapor in the air.
Explanation: Humidity is when a quantity of water vapor is in the atmosphere, likewise, measuring the water vapor in the air would directly define humidity.
Humidity is defined as the measure of the amount of water vapor in the air. Relative humidity and specific humidity are two ways to measure it, with relative humidity being the most commonly used, expressed as a percentage.So,option A is correct.
The correct answer to which of the following defines humidity is A: measure of the amount of water vapor in the air. Humidity is a term used to describe the water vapor content of the air, and it is an important factor in weather and climate. Relative humidity is a common way to express this concept, referring to the ratio of water vapor in the air to the amount of water the air could hold at a given temperature and pressure, often expressed as a percentage. Another measure of humidity is specific humidity, which is the weight of water vapor in the air per unit weight of air, including the weight of water vapor, typically measured in grams of water vapor per kilogram of air.

1) atmosphere and biosphere
2)biosphere and hydrosphere
3) geosphere and biosphere
4) hydrosphere and geosphere
The experiment most likely illustrates how the atmosphere and biosphere interact. As a result, choice (A) is the best way to respond.
What is atmosphere?A layer (or layers) of gases that encircle a planet and are maintained in place by the gravity of the celestial body is known as an atmosphere.When there is a strong gravitational pull and a cool atmosphere, a planet keeps its atmosphere. The outer region of a star, including the layers above the opaque photosphere, is known as the stellar atmosphere; low-temperature stars may have outer atmospheres with complex molecules.
Nitrogen makes up 78% of the atmosphere of Earth, along with oxygen (21%), argon (0.9%), carbon dioxide (0.04%), and trace gases. The majority of species require oxygen for respiration, whereas plants and algae use carbon dioxide for photosynthesis and lightning and bacteria execute nitrogen fixation to create ammonia, which is used to create nucleotides and amino acids.

how does the speed of light change in water compared to air
Answer:
Light travels in waves, and we call this traveling propagation. Propagation of waves has both a speed and a direction, called the velocity. The velocity of light changes depends on the material it travels through.
Light waves can be changed in a few different ways. Reflection is when the waves bounce off a surface and change direction, like when they hit a mirror or pool of water. Diffraction spreads out light waves as well
