Answer:
d = 421.83 m
Explanation:
It is given that,
Height, h = 396.9 m
Horizontal speed, v = 46.87 m/s
We need to find the distance traveled by the ball horizontally. Let t is the time taken by the ball. Using second equation of motion for vertical direction. So,
Now d is the distance covered by the cannonball. So,
Hence, this is the required solution.
Answer:
D.physical model
Explanation:
it is the evolution of butterfly
In making a thermometer used to monitor the temperature of the water, a glass tube, a scale, and a thermometric liquid such as alcohol is required.
<h3>What is a thermometer?</h3>
A thermometer is an instrument that is used to measure or read the temperature of a body or a substance.
There are different types of thermometers such as:
- Liquid-in-glass thermometers
- Gas thermometers
- Resistance thermometers
A simple liquid-in-glass thermometer consists of the following parts:
- A glass tube
- A scale
- A thermometric liquid such as alcohol
Therefor, in making a thermometer used to monitor the temperature of the water, a glass tube, a scale, and a thermometric liquid such as alcohol is required.
In conclusion, a thermometer is the instrument used in measuring temperature.

Answer:
a=g.
the body is in one of these INGRAVIDITY, so the weight of the body would be ZERO
Explanation:
When the spacecraft revolves around the Earth, it is subjected to Newton's second law
F = m a
where the force is the universal attractive force, the mass of the astronauts, and the centripetal acceleration.
a = F / m
a = (G M m / r²) / m
a = G M / r²
the amount of is the acceleration of gravity at height r.
a = g
Therefore, we see that the acceleration of the body is equal to the acceleration of gravity, which is why the body is in one of these INGRAVIDITY, so the weight of the body would be ZERO
