Answer:

The material or substance that a wave moves through is called a MEDIUM. The medium affects the speed of the wave that passes through it. One factor that affects the speed of a wave is the TYPE of medium. Some waves move faster in solids and some waves move faster in liquids and gases. Another factor that affects wave speed is the TEMPERATURE of the medium.

Explanation:

As we know that the speed of the wave is given as

$v = \sqrt{\frac{E}{\rho}}$

here we know that

E = elasticity of the medium

$\rho$ = density of the medium

So here we know that speed of the wave will change with the elasticity of the medium which meas it is the type of medium on which the speed of wave will depends upon.

Another we can say for liquid or gas we can say that

$\frac{E}{\rho} = \frac{\gamma RT}{M}$

so speed will depends on the temperature of the medium

so here answers are

1)Medium

2)Type of medium,

3)Temperature

. A grindstone increases in angular speed from 4.00 rad/s to 12.00 rad/s in 4.00 s. Through what angle does it turn during that

ZanzabumX [31]

Answer:

$\theta=32rad$

Explanation:

In an uniformly accelerated circular motion, the angle traveled by the object is given by:

$\theta=\frac{\omega_f+\omega_0}{2}t$

Here $\omega_f$ is the final angular speed, $\omega_0$ is the initial angular speed and t is the time of the motion. Replacing the given values:

$\theta=\frac{12\frac{rad}{s}+4\frac{rad}{s}}{2}(4s)\\\theta=32rad$

A car accelerates in the +x direction from rest with a constant acceleration of a1 = 1.62 m/s2 for t1 = 20 s. At that point the

arsen [322]

Total displacement of the car: 405 m

Explanation:

The first part of the motion of the car is a uniformly accelerated motion, so we can use the suvat equation

$s_1=ut_1+\frac{1}{2}a_1 t_1^2$

where:

u = 0 is the initial velocity (the car starts from rest)

$t_1 = 20 s$ is the time elapsed in the 1st part

$a_1=1.62 m/s^2$ is the acceleration of the car in the 1st part

$s_1$ is the displacement of the car in the 1st part

Solving for $s_1$ ,

$s_1=0+\frac{1}{2}(1.62)(20)^2=324 m$

We can also find the velocity of the car after these 20 seconds using the equation:

$v_1 = u +a_1 t_1 = 0 + (1.62)(20)=32.4 m/s$

Now we can find the distance covered by the car in the 2nd part, where it decelerates after having seen the tree limb on the road. We can do it by using the suvat equation:

$s_2 = (\frac{v_1 + v_2}{2})t_2$
