Well, the lowest mass a triple beam balance can measure is 0
Answer:
Mg= 1.3418 kg*m/s
Explanation:
Mass of rifle

Recoil velocity of rifle

Momentum of rifle

mass of bullet
mb=7.2x10^{-3} kg=0.0072 kg
velocity of bullet relative to muzzel
v_{b} = 601 m/s
velocity of bullet relative to earth= 601 - 1.95=599.05 m/s
momentum of bullet

the momentum of the propellant gases = momentum of rifle - momentum of bullet
the momentum of the propellant gases
Mg=5.655 -4.3132
Mg= 1.3418 kg*m/s
the momentum of the propellant gases in a coordinate system attached to the earth as they leave the muzzle of the rifle is 1.3418 kgm/s
Answer:
I thinck it would be 48.0
Answer:
792J
Explanation:
Use the formula Force × Distance
With 110 newtons being the force and 7.2 meters being the distance
Which gives 792 and work us measured in joules therefore its joules
Answer:
Explanation:
The theory of plate tectonics suggests that the earth is broken into a series of slabs called lithosphere that moves over the weak asthenosphere below it.
This theory has provided insight to many chimerical observations made in earth science like volcanism, earthquakes, orogeny e.t.c.
Theory came into limelight after the second world war based on the precepts of the continental drift theory and sea floor spreading theory.
Mantle convection provides the mechanism of motion for the moving plates.
- We can explain the presence of fossils of the same plants and animals in locations that are different using this theory.
- Once in time, the earth was a united land mass.
- Therefore, geographical distribution of fossils across different terrain was not limited.
- It was after the separation of the plates that diversity started.
