The gravitational field is the Force divided by the mass
Call g the gravitational fiel, F the force exerted by the earth and m the mass of the telescope.
g = F / m
g=9.1x10^4 N / 1.1 x 10^4 kg = 8.27 N/kg
Note that the unit N/kg is equivalent to m/s^2
Answer:1207.811 KPa
Explanation:
Given
Nozzle and hose are at same level thus
Applying Bernoulli's equation
thus
Also discharge (Q)=AV
Answer:
(d) −7 C
Explanation:
Like charges attracts and unlike charges repel. When the three charges are are agitated, the +3 C and +4 C will repel to give of +7 C. To create a balance in the system, the third charge will -7 C to give an algebraic sum of zero in the system.
Answer:
Explanation:
The final angular speed of the system is given by the help of the Principle of the Angular Momentum Conservation:
The final angular speed is:
Finally, the change in the rotational kinetic energy is:
So I’m gonna answer the first question on the second page:
For P the force is friction and for Q the force is forward thrust resultant force
