To solve this problem we will apply Newton's second law and the principle of balancing Forces on the rope. Newton's second law allows us to define the weight of the mass, through the function
Here,
m = mass
a = g = Gravitational acceleration
Replacing we have that the weight is
Since the rope is taut and does not break, the net force on the rope will be zero.
Therefore the tensile force in the rope is 98N
Answer: work done = 64,000J or 64KJ.
Explanation:
Work is said to be done if a force applied makes the object to move through a distance in the direction of the applied force. Work is the product of force and perpendicular distance in the direction of the applied force. It is represented by W, measured in Joules(J) and a scalar quantity.
Thus, work done(J)= force(N) × distance(m)
From the the question,
applied force= 1600N
distance=40m
Therefore, work= 1600 × 40
W= 64,000J
But, 1 kilojoules = 1000J
Therefore, 64,000J = 64,000 ÷ 1000
= 64KJ
Work done is 64KJ
Here (X) is a parallel combination of resistors whereas it is series combination of resistors in (Y).
Hope this is the answer you're looking for. If it is correct then mark my answer as the brainliest! :)
Answer:
building A because the insulation will keep the air in the building while more so building b will let the air flow out because there is no insulation
Explanation:
The Doppler effect helps aid in forecasting the velocity of objects.
This could include precipitation in the atmosphere!
