Answer:
the car accelerates in
Explanation:
here's the solution : -
we know,
=》
=》
=》
=》
so, acceleration = 1500 m/s^2
now,
=》
here, a = acceleration, v = final velocity,
u = initial velocity, t = time taken.
So,
=》
=》
=》
=》
They did not affect Florida- never came that far South.
Transpiration is the evaporation of water from plants. This occurs when water drawn from the roots is brought up the leaves (as it usually should), and, because of the outside heat, it vaporizes and exits via the pores found on the underside of the leaves.
Answer:
The electric field at the location of the point charge is defined as the force F divided by the charge q: Figure 23.1. Electric force between two electric charges. The definition of the electric field shows that the electric field is a vector field: the electric field at each point has a magnitude and a direction.
Answer:
for the body to float, the density of the body must be less than or equal to the density of the liquid.
Explanation:
For a block to float in a liquid, the thrust of the liquid must be greater than or equal to the weight of the block.
Weight is
W = mg
let's use the concept of density
ρ_body = m / V
m = ρ_body V
W = ρ_body V g
The thrust of the body is given by Archimedes' law
B = ρ_liquid g V_liquid
as the body floats the submerged volume of the liquid is less than or equal to the volume of the block
ρ_body V g = ρ_liquid g V_liquid
ρ_body = ρ liquid Vliquido / V_body
As we can see, for the body to float, the density of the body must be less than or equal to the density of the liquid.
