Thermal energy transformation is taking place.
An eclipse is a phenomenon of an astronomical object being obscured by something. In this case, it is the Moon that is being obscured from sunlight by Earth's shadow. Answer is D.
Answer:
F = 104.832 N
Explanation:
given,
upward acceleration of the lift = 1.90 m/s²
mass of box containing new computer = 28 kg.
coefficient of friction = 0.32
magnitude of force = ?
box is moving at constant speed hence acceleration will be zero.
Now force acting due to lift moving upward =
F = μ m ( g + a )
F = 0.32 × 28 × ( 9.8 + 1.9 )
F = 104.832 N
hence, the force applied should be equal to 104.832 N
Answer:
52 mL
Explanation:
Since the pressure of the gas remains constant, we can use the following gas law:
where:
is the initial volume
is the final volume
is the initial temperature
is the final temperature
Substituting numbers and re-arranging the equation, we find the final volume of the gas:
So the correct answer is
1. 52 mL
