Force D.
Gravity points downward.
Answer:
D) The ball exerts a force on the wall and the wall exerts a force back.
Explanation:
Newton's third law of motion states that:
"When an object A exerts a force on another object B, then object B exerts an equal and opposite force on object A"
In this problem, we can identify (for instance) object A with tha ball and object B with the wall. Therefore, if we apply Newton's third law, we get:
The ball (object A) exerts a force on the wall (object B), therefore the wall (object B) exerts an equal and opposite force on the ball (object A). So, option D is the correct one.
Answer:
The wavelength of wave is 7.5 meter.
Given:
Speed of wave = 1500
Frequency of wave = 200 Hz
To find:
Wavelength of wave = ?
Formula used:
Where = wavelength of the wave
v = speed of wave
n = frequency of wave
Solution:
Wavelength of wave is given by,
Where = wavelength of the wave
v = speed of wave
n = frequency of wave
= 7.5 m
The wavelength of wave is 7.5 meter.
Standard temperature is equal to 0 °C<span>, which is 273.15 K. Standard Pressure is </span>1 Atm<span>, 101.3kPa or </span>760 mmHg<span> or torr. STP is often used for measuring gas density and volume. At STP 1 mole of any gas occupies 22.4L.
Hope this helps. :)</span>
Inner planets are far warmer than outer planets. Due to distant of the sun
As the planets distant from the sun. The colder the get due to distance.
