Answer:
Position at t= 4 seconds is 144 m
Explanation:
It is given that acceleration, a = 18 t, where t is the time.
We know that Velocity,
Substituting value of a,
Velocity,
We know that at t = 0, v = -12 m/s
So,
So velocity,
We also know that displacement,
Substituting value of v,
Displacement,
We know that at t = 0, particle is at origin, x =0.
So,
Displacement,
At t = 4 seconds
Position at t= 4 seconds is 144 m

Answer :
(a). The speed of the block is 0.395 m/s.
(b). No
Explanation :
Given that,
Diameter = 20.0 cm
Power = 26.0 MW
Mass = 110 kg
diameter = 20.0 cm
Distance = 100 m
We need to calculate the pressure due to laser
Using formula of pressure
We need to calculate the force
Using formula of force
Put the value into the formula
We need to calculate the acceleration
Using formula of force
Put the value into the formula
(a). We need to calculate speed of the block
Using equation of motion
Put the value into the formula
(b). No because the velocity is very less.
Hence, (a). The speed of the block is 0.395 m/s.
(b). No
The oxygen atom in a water molecule has the greatest and or highest electronegativity, it has the greatest ability of all of the elements in a water molecule, 2, to pull electrons closer towards its own atom.
