Answer:
Part a)
Part b)
Explanation:
As we know that torque is defined as the product of force and its perpendicular distance from reference point
so here we have
now we have
Part b)
Now we know the conversion as
1 meter = 3.28 foot
1 N = 0.225 Lb force
now we have
Correct option: D. Earthquakes along the San Andreas fault in California.
The earthquakes occur when the two plates collide with each other. Hence, there is contact between the two plates. So, the contact forces are responsible for the earthquakes.
The force responsible for Jupiter's moons to stay in orbit or the high tides occurring on the east coast is the gravitational force, which is not a contact force as there is no contact between Jupiter and its moon or the earth and the moon which is responsible for the high tides.
Moreover, the magnetic force is a non contact force as it attracts the pins from a distance without any contact between them.
Answer:
No .
Explanation:
The vapor pressure of water at room temperature is .0313 atom or 3.13 kPa.
To make a liquid boil, its vapor pressure must be equal to pressure around it.
So pump must create pressure of 3.13 k Pa or less to make water attain its stage of boiling at room temperature. As the motor can not produce pressure lesser than 15 k Pa , pump will not be able to make water boil at room temperature.
