Answer:
Its velocity is 16.5 feet/sec
Explanation:
Since the depth of the water 'd' (in feet) and the velocity of the wave 'v' (in feet per second) are related by the equation
v = √(32d)
a wave forms in water with a depth of 8.5 feet, therefore <em>d = 8.5 ft</em>
velocity = √(32 x 8.5)
= √272
= 16.49 feet/sec
≈ 16.5 ft/s
Answer:
The average surface temperature decreases the further you get from the Sun because the more distant planets receive less energy/heat/sunlight per square meter of their surface. This is because the energy from the Sun spreads out (becomes less concentrated) as you travel further from the source/Sun.
Explanation:
Answer:
the height h is 1.95 m above the floor
Explanation:
m = 2.0 kilogram
Ep = 39 J
g = 10 m/s²
h = ?
Ep = mgh
h = Ep ÷ mg
h = 39 ÷ (2×10)
h = 39÷20
h = 1.95 m
The acceleration of the car is determined as 0.626 m/s².
<h3>
What is acceleration?</h3>
The acceleration of an object is the change in velocity of the object with time.
a = Δv/t
where;
- Δv is change in velocity
- t is the time of motion
Substitute the given parameters and solve for the acceleration.
v = 14 mph = 6.258 m/s
a = (6.258 m/s) / (10 s)
a = 0.626 m/s²
Thus, the acceleration of the car is determined as 0.626 m/s².
