Not so fast! If a force of 2500 N is used over

Masteriza [31]

Answer:

B 1500N

Explanation:

The acceleration of the car - at least the average one, but that will do, is $a= \frac{\Delta v}{\Delta t} = \frac 53 ms^{-2} = 1.66 ms^{-2}$

We know the acceleration, we know the force, let's drop them in Newton second law.

$F= ma = 2500= m \frac53 \rightarrow m=500\times 3 N = 1500N$

What is the pressure exerted by a column of fresh water 10m high (p=1000kg/m3 and g=10m/s)

alexira [117]

Height (h) = 10 m
Density (ρ) = 1000 Kg/m^3
Acceleration due to gravity (g) = 10 m/s^2
We know, pressure in a fluid = hρg
Therefore, the pressure exerted by a column of fresh water
= hρg
= (10 × 1000 × 10) Pa
= 100000 Pa

Answer:

100000 Pa
