The gravitational field intensity (EG) or (g) is the force on a unit mass at a point in the field.
Since the force (F) on a body of mass m in a gravitational field of a body of mass M = GMm/r2 .
you can see that the force per unit mass is given by F/m. So:
Gravitational Field Intensity (EG) = (g) = F/m = GM/r2
The units for EG are N kg -1 or since F = ma, F/m = a and so EG may be expressed in ms -2
Hope this will help you :))
Do give this answer a brainliest :D
Acceleration is the rate of change of velocity, so can be calculated by:
a = v2 - v1 / t where v2 and v1 are the final and initial velocities of the object respectively and t is the time taken. Therefore the acceleration is:
a = 30 m/s - 20 m/s / 2.0 s = 10 m/s / 2.0 s = 5 m/(s^2)
Hope this helps!
The correct option is D.
Because <span>the distance that the honey flows is a dependent variable. Becuase the coefficient of viscosity is dependent on the velocity gradient (v/L). And, </span>Viscosity is very temperature dependent • It decreases with increasing temperature (in case of liquids). But, Viscosity of a gas increases with increasing temperature.
In a distance vs time graph what does the slope represents the Velocity
The question can be solved using conservation of linear momentum.
= 0.06kg and 
= 0.03kg
Let the initial velocity of Marble A be , 
= 0.7m/s
Let the initial velocity of Marble B be, 
= 0m/s
Let the velocity of Marble A after collisiong , 
= -0,02m/s
Let the velocity of Marble B after collision be 
From the conservation of linear momentum equation. We get,
Substituting the values we get,
(0.06)(0.7) + 0 = (0.06)(-0.02) + (0.03)
we get, = 1.44m/s
