A 1,200 kg subcompact car accelerates at a rate of 3.0m/s

1 answer:

6 0

Missing question (found on internet):
"what is the force of the car?"

Solution:
According to Newton's second law, the force of the car is equal to the product between its mass and its acceleration:
$F=ma$
For the car in the problem,
$m=1200 kg$
$a=3.0 m/s^2$
So the force that accelerates the car is
$F=(1200 kg)(3.0 m/s^2)=3600 N$

an object was accelerated with a force of 150 N from rest to a velocity of 10m/s in 5 sec. the force of friction opposing the ob

astra-53 [7]

Force = (mass) x (acceleration)

Mass = (force) / (acceleration)

There was 150N of force in one direction and 100N of 'force' in
the other direction. The net force on the object was (150 - 100) = 50N .

Acceleration = (change in speed) / (time for the change)
= (10 m/s) / (5s) = 2 m/s²

Mass = (net force) / (acceleration) = (50 N) / (2 m/s²) = 25 kilograms

irina1246 [14]

Answer:

ventriculoperitoneal

Explanation:

A VP or ventriculoperitoneal shunt is a medical equipment or a device which is used to relieve pressure from the brain that is caused by the accumulation of fluid in the brain. Ventriculoperitoneal shunting is a medical procedure that is primarily used to treat a condition known as hydrocephalus. This condition occurs when the more cerebrospinal fluid (CSF) gets collected in the ventricles of the brain than required.

Hence the answer is ---

ventriculoperitoneal

Suppose a plot of inverse wavelength vs frequency has slope equal to 0.119, what is the speed of sound traveling in the tube to

strojnjashka [21]

Answer:

8.40 m/s

Explanation:

Slope of the plot is 0.119

Slope of a plot is given by the change in y direction divided by the change in x direction

Here, the y axis represents inverse wavelength and the x axis represents frequency.

f = Frequency (Hz, assumed)

v = Phase velocity (m/s, assumed)

λ = Wavelength (m, assumed)

So, slope

$m=\frac{\frac{1}{\lambda}}{f}$

Now,

$\lambda=\frac{v}{f}\\\Rightarrow \lambda^{-1}=\frac{f}{v}$

$\\\Rightarrow m=\frac{\frac{f}{v}}{f}\\\Rightarrow 0.119=\frac{1}{v}\\\Rightarrow v=\frac{1}{0.119}\\\Rightarrow v=8.40\ m/s$

The speed of sound travelling in the tube is 8.40 m/s
