Answer:

Explanation:
Acceleration, 
Where v and u are the final and initial velocities of the race car respectively, t is the time taken for the race car to attain velocity of 36 m/s.
Substituting 36 m/s for v, 28 m/s for u and 2 s for t then

Answer:
The wavelength of the sound waves are, λ = 26.92 m
Explanation:
Given data,
The frequency of the sound waves, f = 13 Hz
The speed of sound waves in air, v = 350 m/s
The velocity of the wave in the medium is equal to the product of its wavelength and its frequency.
The formula for the wavelength of the waves is,
λ = v / f
Substituting the given values in the above equations,
λ = 350 m/s / 13 Hz
= 26.92 m
Hence, the wavelength of the sound waves are, λ = 26.92 m
The projectile maintains its horizontal component of speed because there's nothing exerting any horizontal force on it. <em>(b) </em>
Gravity has no effect on horizontal motion.
T(°C) = (T(°F) - 32) × 5/9
T(°F) = T(°C) × 9/5 + 32
The magnitude of the angular momentum of the two-satellite system is best represented as, L=m₁v₁r₁-m₂v₂r₂.
<h3>What is angular momentum.?</h3>
The rotational analog of linear momentum is angular momentum also known as moment of momentum or rotational momentum.
It is significant in physics because it is a conserved quantity. the total angular momentum of a closed system remains constant. Both the direction and magnitude of angular momentum are conserved.
The magnitude of the angular momentum of the two-satellite system is best represented as;
L=∑mvr
L=m₁v₁r₁-m₂v₂r₂
Hence, the magnitude of the angular momentum of the two-satellite system is best represented as, L=m₁v₁r₁-m₂v₂r₂.
