Answer:
output work is not possible to have more than 294 kJ value so this is not reasonable claim
Explanation:
As we know that the efficiency of heat engine is given as
now we will have
now we know that efficiency is defined as
So output work is not possible to have more than 294 kJ value

Explanation:
The force of gravity between the apple and the baseball is 3.335×10¯¹¹ N
The following data were obtained from the question given above:
Mass of apple (M₁) = 1 Kg
Mass of baseball (M₂) = 2 Kg
Distance apart (r) = 2 m
Gravitational constant (G) = 6.67×10¯¹¹ Nm²/Kg²
<h3>Force (F) =? </h3>
The force of gravity between them can be obtained as follow:
Therefore, the force of gravity between them is 3.335×10¯¹¹ N

Explanation:
From the question we are told that
The diameter of the Ferris wheel is
The period of the Ferris wheel is
The mass of the passenger is
The apparent weight of the passenger at the lowest point is mathematically represented as
Where is the centripetal force on the passenger, which is mathematically represented as
Where is the angular velocity which is mathematically represented as
substituting values
and r is the radius which is evaluated as
substituting values
So
W is the weight which is mathematically represented as
So
The apparent weight of the passenger at the highest point is mathematically represented as
substituting values
Answer:
Maximum 13 m overhang
Explanation:
Since the brick is uniform. Its mass must be equally distributed along its length. So the center of mass is in geometric center, which is 26 / 2 = 13 m from each end of the brick.
For the brick to not tip over, its center of mass must NOT be overhung over the edge. It stays just on the edge. So the maximum overhang is 13 m.
