Answer:
v = 16.98 km/s
Explanation:
Given that,
Distance, d = 4500 km
Time, t = 265 s
We need to find its average speed. The total distance covered divided by total time taken is called average speed of an object. So,
So, the average speed is 16.98 km/s.
Given that,
Depth of seawater, h = 11,033 m
Density seawater, p (rho) = 1025 kg/m³
Gauge Pressure , P = ??
Since, we know that:
Pressure, P = pgh
Pressure = 1025 * 9.81 * 11033
Pressure = 1109395723.3 N/m²
or
Pressure = 1.1 x 10∧8 Pascal
Answer:
Yes
Explanation:
Newton's third law
For every action, there is an equal and opposite reaction.
SO if the apple is falling 9.8 m/s2 then the same force is pushing against it.

Answer:
4J
Explanation:
Hooke's Law states:
F = -kx
where F = force
k = spring constant
x = displacement of spring
20 = -(50)x
-20/50 = x = -2/5
We can now use this information to find the energy in the Elastic Potential Energy Formula which is...
1/2(k)(x)^2
1/2(50)(2/5)^2 = 4J
