What impulse occurs when an average force of 7.0 N is exerted on a cart for 2.5 s ?

makkiz [27]

Answer: $1.7\times 10$

Explanation:

Given

Force $F=7 N$

time interval $t=2.5 s$

Impulse is given by $=Force \times time\ interval\ for\ applied\ force$

$Impulse=7\times 2.5=17.5$

For two significant Figure

$Impulse=1.7\times 10$

A car accelerates at a rate of 6m/s^2 for 4 seconds until it has traveled a total of 40m what was the initial velocity of the ca

s344n2d4d5 [400]

Using the 2nd equation of motion;

= s = ut + ½at²

= 40 = u×2 + ½ × 6 × 2²

= 40 = 2u + 3 × 4

= 40 - 12 = 2u

= 28/2 = u

= 14 m/s = u

And its done! Simple isn't? :P

A person shouting at the top of his lungs emits aboue 1.0 w of energy as sound waves. What is the sound intensity 1.0 m from suc

umka21 [38]

Answer:

$I=0.0795\ W/m^2$

Explanation:

When a person shouts it emits 1 W of energy as sound waves, P = 1 W

Let I is the sound intensity 1 meters from such a person. We know that the power per unit area is called the sound intensity of the person. Its formula is given by :

$I=\dfrac{P}{A}$

$I=\dfrac{P}{4\pi r^2}$

$I=\dfrac{1\ W}{4\pi (1\ m)^2}$

$I=0.0795\ W/m^2$

So, the sound intensity of such a person is $0.0795\ W/m^2$ . Hence, this is the required solution.
