Answer:
Tension, T = 1736 N
Explanation:
It is given that,
Mass of bricks, m = 175 kg
A rope is attached to a load of 175 kg bricks lifts the bricks with a steady acceleration of 0.12 m/s² in vertically upwards direction. let T is the tension in the rope. Using second equation of motion as :
T - mg = ma
T = ma + mg
T = m(a + g)
T = 175 kg ( 0.12 m/s² + 9.8 m/s² )
T = 1736 N
Hence, the tension in the wire is 1736 N.
Answer: The total rate of heat transfer from the container to its surroundings ignoring radiation is 332.67 W.
Explanation:
Given: Inner diameter = 0.9 m
q = 872
Now, radii is calculated as follows.
Hence, the rate of heat transfer is as follows.
where,
V = volume of sphere =
Substitute the values into above formula as follows.
Thus, we can conclude that the total rate of heat transfer from the container to its surroundings ignoring radiation is 332.67 W.
