Answer:
<em>It takes 3 seconds to reach its high point</em>
Explanation:
<u>Projectile Motion</u>
In a projectile motion (or 2D motion), the object is launched with an initial angle θ and an initial velocity vo.
The components of the velocity are
The speed in the horizontal direction at any time t is:
The time taken to reach the maximum height is when vy=0, or:
We are given the y-component of the velocity, thus:
It takes 3 seconds to reach its high point
Weight is the force applied on the planet by its mass. The weight of an object is 6 times lighter than that of the earth. Option C is correct.
What is Wight?
- It is the product of the mass and the gravitational acceleration.
- Weight is the force applied on the planet by its mass.
The formula of weight is,
Where,
- weight
- mass
- gravitational acceleration
In the question given here the gravitational acceleration of the moon is 6 times less than that of the earth.
Therefore, the weight of an object is 6 times lighter than that of the earth.

The increasing order of the wavelength from left to right are as follows Gamma Rays < X-rays < UV rays < visible rays < infrared rays < microwaves < radio waves.
The electromagnetic spectrum consists of many waves which are made up of electric field and the magnetic field.
It is said that the electromagnetic wave behaves like particle as well as the wave.
The particle like pieces of the wave are called photons which contains the energy of the wave and the electromagnetic waves are primarily decided by the wavelength and the frequency of the wave.
The group of electromagnetic waves are known as electromagnetic spectrum.
The electromagnetic wave in the order of increasing wavelength are Gamma Rays < X-rays < UV rays < visible rays < infrared rays < microwaves < radio waves.

D because it has the lowest wavelength, meaning the wave is the longest. Its crest are more spaced out creating lower energy. The smaller distance between the crests equals the higher the sound. Creating higher energy.
I am 95% sure this is right. Very sorry if it isn't.
Hope it helps. ;3
