Answer:
1Burning of fossil fuel
2Deforestation
3Waste disposal in landfills
Explanation: took test:)
The time taken is
Explanation:
The motion of the bullet is a uniform motion (=constant velocity), therefore we can use the following equation:
where
v is the speed of the bullet
d is the distance covered
t is the time taken
For the bullet in this problem,
d = 0.30 m is the distance travelled
v = 800.0 m/s is the speed
Solving for t, we find the time taken:

Answer:
Explanation:
It is given that,
Force due to rope 1,
Force due to rope 2,
Let is the angle must a third rope tension be applied in order to keep the boat at rest. It can be given by :
The angle clockwise from the positive x-axis will be equal to,
So, the angle must a third rope tension be applied in order to keep the boat at rest is 156.81 degrees. Hence, this is the required solution.
The medium whose light have the longest wavelength is air.
<h3>What is wavelength?</h3>
The wavelength is the distance between the adjacent crest or trough of the sinusoidal wave. The wavelength is the reciprocal of the frequency of the wave.
Wavelength λ = v/f
where v is the speed of wave in medium.
Given is the chart shows the speed at which light travels through different media.
Medium Speed of light in m/s
Water 2.25 x 10⁸
Air 2.99 x 10⁸
Glass 1.97 x 10⁸
Diamond 1.24 x 10⁸
The speed of light is directly proportional to the wavelength. Greater the speed, greater will be the wavelength.
From the chart, air has the highest speed of light.
Thus, the medium whose light have the longest wavelength is air.
