The kinetic energy of a body with a mass of 30 kg and a speed of 10 m/s is 1500 kg m²/s².
In physics, the kinetic energy of аn object is the form of energy thаt it possesses due to its motion. In the case above, we are given the formula for kinetic energy:
KE = 0.5 * m * v²
where m is mass and v is speed. And we are given m = 30 kg and v = 10 m/s.
To calculate the kinetic energy, we simply plug in the values of m and v into the formula:
KE = 0.5 * 30 kg * (10 m/s)²
Simplifying the equation gives:
KE = 0.5 * 30 kg * 100 m²/s²
KE = 15 kg * 100 m²/s²
KE = 1500 kg m²/s²
Therefore, the kinetic energy of the body is 1500 kg m²/s².

Answer:
The kinetic energy of a body mass of 30 kg traveling in space at a speed of 10 m/s can be calculated with the formula KE = 0.5 * m * v^2, where m is the mass of the body and v is the speed. In this case, the kinetic energy would be equal to 0.5 * 30 * 10^2 = 1500 Joules.
A. Gases missing with particles
B. liquid moving through a vacuum
C. moving Particles
D. Electromagnetic waves
The correct answer to the question is D. Electromagnetic waves.
EXPLANATION:
As per the diagram, the radiations are emitted by sun is coming to earth.
The radiations coming from sun is electromagnetic in nature. It does not require any medium for its propagation. It travels a long distance in vacuum or space to reach earth.
It contains both electric field and magnetic field which are perpendicular to each other and also normal to the direction of propagation. The diagram shows that the wave is moving in the form of crests and troughs.
If we consider the wave nature of radiation, then it is one way of transportation of thermal energy from sun to earth which is known as radiation.
Hence, the arrows drawn in the figure is electromagnetic waves.
