Answer:
Explanation:
Block A sits on block B and force is applied on block A . Block A will experience two forces 1) force P and 2 ) friction force in opposite direction of motion . Block B will experience one force that is force of friction in the direction of motion .
Let force on block A be P . friction force on it will be equal to kinetic friction, that is μ mg , where μ is coefficient of friction and m is mass of block A
friction force = .4 x 2.5 x 9.8
= 9.8 N
net force on block A = P - 9.8
acceleration = ( P - 9.8 ) / 2.5
force on block B = 9.8
acceleration = force / mass
= 9.8 / 6
for common acceleration
( P - 9.8 ) / 2.5 = 9.8 / 6
( P - 9.8 ) / 2.5 = 1.63333
P = 13.88 N .
Answer:
quantity A is mass and quantity B is wright
Answer:
<h2>7.21 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 2.060 × 3.5
We have the final answer as
<h3>7.21 J</h3>
Hope this helps you
Answer:
356K
Explanation:
use this formula for brayton cycle
∩=1-(Tin/Tout)
where
∩=efficiency
Tin= inlet temperature
Tout=
outlet temperature
solving
Tout=Tin/(1-∩)
Tout=267K/(1-0.25)
Tout=356K
