Answer:
area is the space bounded by certain lines, the SI unit of area is m²
area of rectangle =l×w×h
square=l²
Answer: Acted on by equal forces in opposite direction
Explanation:
Newton's First Law says that every body continue in its state of rest or constant speed on a straight line unless being acted upon by an external force.
Answer:
28,126pascal
Explanation:
Hydrostatic pressure exerted on the bottom of the tank can be calculated using the formula
P = hpg where;
h is the depth of the tank = 3.5m
p is the density of the kerosene = 820kg/m³
g is the acceleration due to gravity = 9.8m/s²
Substituting the values into the formula we have;
P = 3.5×820×9.8
P = 28,126Pascal
Answer:
Zero
Explanation:
It is given that the charge is uniformly spread at the surface of hollow spherical shells.
There is no charge with in the hollo shell. hence, with zero charge the electric field intensity is also zero.
Thus,
Magnitude of the electric field strength inside the hollow shell at r is zero
