Answer:
d
Explanation:
i think it is rotational inertia
because analogue of mass in rotational motion is moment of inertia. It plays the same role as mass plays in transnational motion.

Hi pupil Here's your answer ::::

The sun Doesnt rotates as we know all . But it rotates with the wjole our Milky Way Galaxy. This movement is so slow that we cant even recognise that we are shifted.
This we know because we all had studied about the solar system and space.
By this study we can say that Sun Rotates.

Answer:
a.
b. decrease
c. 43.5psi
Explanation:
Answer:
a.
Explanation:
from the questions, the car has four tires which support the weight equally.we can conclude that the weight support by each tire is
weight support of each tire =1420/4=355kg.
a. since
we need to determine the force,
the "g" is the acceleration due to gravity which has a constant value of
hence the force on each tire is
Also, since the pressure is giving in psi, we have to convert it to pascal
since 1psi=6895pascal
hence 35psi to pascal is
.
From the expression for pressure
we have
to cm we multiply by
b. The effect of the pressure can be determine from the relationship between the pressure and the area using the pressure formula
hence an increase in the pressure will lead to a decrease in the contact Area
C. if the area ia now converting to meter square
the pressure now is
converting to psi we have
