Answer:
Step-by-step explanation:
Given that,
Initial speed of a vehicle, u = 25 km/hr = 6.95 m/s
Final speed of a vehicle, v = 1200 km/hr = 333.34 m/s
Time, t = 60 s
We need to find the acceleration of the vehicle. It is equal to the rate of change of velocity. It can be given by :
So, the acceleration of the vehicle is 
.
F = k / (r^2)
dF/dt = -2k / (r^3) dr/dt
When r = 10^4 km and dr/dt = 0.2 km/sec
dF/dt = -2(10)^3 (0.2) / ((10^4)^3) = -400 / 10^7 = -0.00004 N/s
The gravitational force is changing at the rate of -0.00004 N/s
Answer:
30 units²
Step-by-step explanation:
Area of a parallelogram = Base * Height
Substitute in known values
Area = 6 * 5
Area = 30 units²
