Answer:
the magnitude of gravitational force is very small according to the magnitude of electric force.
Explanation:
GIVEN:
electric force (E) ----> 2×10⁴ N/C
charges (q•) ----> 1.6×10-¹⁹ C
[ it's a proton +ve charges due to the direction along positive X-axis]
mass of the protons (m) ----> 1.67×10-²⁷ kg
acceleration due to gravity (g) ----> 9.8 m/sec²
The Joule is a unit of energy, not Force
Capacity of a freezer is actually the volume.
so it will be equal to width*length*depth= 2*4*30= 240 Answer
Answer:
remain stationary
Explanation:
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
Answer:
Gauge Pressure required = 606.258 kPa
Explanation:
Water will not enter the chamber if the pressure of air in it equals that of the water which tries to enter it.
Thus at a depth of 60m we have pressure of water equals
Now the gauge pressure is given by
Applying values we get
