3.4 × 10³ N.
<h3>Explanation</h3>
The perpendicular distance between the 400 N force and the fulcrum is .
What's the perpendicular distance between the friction of the nail and the fulcrum?
Refer to the diagram attached. The perpendicular distance between the nail and the fulcrum is .
What's the size of the friction of the nail?
.
Answer:
Below
Explanation:
Here is how to find the Fnet of the plate :
Fnet = F1 + F2
Fnet = 100 N [ R ] + 75 N [ L ]
Now because the forces push in opposite directions, you need to subtract :
Fnet = 100 N [ R ] - 75 N [ R ]
Fnet = 25 N

Answer:
horse power of the truck 39,000 kgm²s⁻³
Explanation:
Calculate horse power of the truck.
Work = force x distance
where, force = mg = 2000 kg x 9.8 m/s² = 19,600 kgm/s²
distance = 10 meter
Work = 19,600 kgm/s² x 10 meter
= 196,000 kgm²s⁻²
Power = work / time
= 196,000 kgm²s⁻² / 5 seconds
= 39,000 kgm²s⁻³
Answer:
The acceleration produced is
Explanation:
By the second law of Newton, the force F is equal to:
F = ma
Where m is the mass of the object and a is the acceleration produced. So if The force gives the standard 1 kg mass an acceleration of 1.00 m/s2, that means that the force apply on A and B is equal to:
F = (1Kg) * (1.00m/s2) = 1 N
Then, if this force on A produce an acceleration of 0.530 , the mass of A is:
At the same way, if this force on B produce an acceleration of 0.344 , the mass of B is:
Therefore, if they are attached and the same force is applied, the acceleration is:
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.
