Answer:
Explanation:
Given that,
Mass of the astronaut, m = 70 kg
Mass of the spacecraft,
Acceleration of the astronaut,
To find,
The magnitude of the acceleration of the spacecraft.
Solution,
The force acting on the astronaut is given by :
During the push, the astronaut accelerates as a result a reaction force will also act on the spacecraft. Let is the acceleration of the spacecraft. It can be calculated as :
(reaction force)
Therefore, the magnitude of the acceleration of the spacecraft is . Hence, this is the required solution.
1) The tension in the horizontal massless cable CD is, 446N
2) The vertical component of the force exerted by the pivot A on the aluminum pole 328.3N
3)The horizontal component of the force exerted by the pivot A on the aluminum pole is,446N
To find the answer, we need to know about the tension.
<h3>How to find the tension in the horizontal massless cable CD?</h3>
- To find the tension in horizontal cable CD ,we have to draw the free body diagram of the masses.
- Given that,
- In the free body diagram, let's balances all the vertical and horizontal forces to get the tension on CD.
<h3>How to find the vertical and horizontal components of the force exerted by the pivot A on the aluminum pole?</h3>
- The net force along vertical direction can be written as,
- The net force along the horizontal direction is,
Thus, we can conclude that, the tension in the horizontal massless cable CD and the horizontal component of force exerted by the pivot A on the aluminum pole are same and is equal to 466N, and the vertical component force exerted by the pivot A on the aluminum pole is 328.3N.

Answer:
Explanation:
The simplest circuit has the battery in series with the resistor
V = IR
I = V/R = 1.5 / 15 = 0.10 Amps
It could be 1.5 / 150 = 0.01 A depending on how one assumes an error or not in "150hm"
Answer:
Explanation:
The process is isothermic, as P V = constant .
work done = 2.303 n RT log P₁ / P₂
= 2.303 x 5 / 29 x 8.3 x 303 log 2 / 1 kJ
= 300.5k J
This energy in work done by the gas will come fro heat supplied as internal energy is constant due to constant temperature.
heat supplied = 300.5k J
specific volume is volume per unit mass
v / m
pv = n RT
pv = m / M RT
v / m = RT / p M
specific volume = RT / p M
option B is correct.
