The lighter one travel with the speed of 0.574 m/sec. Force is defined as the product of mass and acceleration. Its unit is Newton.
<h3>What is force?</h3>
Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body.
The two skaters push off against each other on frictionless ice, then torque act by the one skater on the other is equal.
P₁₂=P₂₁
F₁₂V₁ =F₂₁V₂
625 ×V₁= 725 N× 1.5 m/s
V₁=0.574 m/sec
Hence, the lighter one travel with the speed of 0.574 m/sec.

Answer:
Area of the rectangular field in kilometers is 0.09
Explanation:
We know that 1 kilometers = 1000 meters
since we need to find the area in unit of kilometers
therefore converting length and width into kilometers
1000 meters = 1 kilometers
300 meters =
Likewise width = 0.3 km
Area = length x width
= 0.3km x 0.3 km
= 0.09
The answer is d. Wavelength
