Answer:
The boat's acceleration is 4 m/s²
Explanation:
This question seeks to test the knowledge of acceleration and how to calculate acceleration when the speed is provided. Hence, the formula for acceleration would be used here.
Acceleration (m/s²) = speed (in m/s) ÷ time (in seconds)
Acceleration = 80 m/s ÷ 20 secs
Acceleration = 4 m/s² or 4 ms⁻²
The boat's acceleration is 4 m/s²
Answer:

Explanation:
Pressure does not depends on the shape of the container
Pressure acting all direction
Answer:
Any object that is being acted upon only by the force of gravity is said to be in a state of free fall.
Explanation:
The non-relativistic formula for kinetic energy for low speeds is :
K.E = 0.5mv^2 = 0.5 * 22 * (5)^2 = 275 J
Answer:
134 f
Explanation:
The hottest temperature ever reliably measured in a desert was 134 degrees F, in Death Valley of the Mojave Desert in 1913.
