Answer:

Gamma rays

Explanation:

Gamma rays are usually defined as a type of electromagnetic radiations, that are characterized by the presence of shorter wavelength and higher energy. These are the common radiations that are released from the radioactive substances, where an unstable nucleus of an atom releases an excess amount of energy by undergoing continuous electromagnetic processes.

These are harmful to humans and other organisms, as they are comprised of very high energy and they can easily penetrate through the bodies of humans and other organisms.

These gamma particles are emitted in the power plants, where the people working in it wear a special type of device that helps them in monitoring the exposure to radiation.

A 8.34 × 103-kg lunar landing craft is about to touch down on the surface of the moon, where the acceleration due to gravity is
Mnenie [13.5K]

Answer:

21870.3156 N

Explanation:

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

g = Acceleration due to gravity = 1.6 m/s²

Equation of motion

v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{0^2-18.2^2}{2\times 162}\\\Rightarrow a=-1.02234\ m/s^2

The acceleration of the craft should be 1.02234 m/s²

F=ma\\\Rightarrow F=8.34\times 10^3\times 1.02234\\\Rightarrow F=8526.3156\ N

Weight of the craft

W=mg\\\Rightarrow W=8.34\times 10^3\times 1.6\\\Rightarrow W=13344\ N

Thrust

F_t=F+W\\\Rightarrow F_t=8526.3156+13344\\\Rightarrow F_t=21870.3156\ N

The thrust needed to reduce the velocity to zero at the instant when the craft touches the lunar surface is 21870.3156 N
