Explanation:

High pitch due to high frequency b/c of doppler effect. The sound waves in front of the vehicle are being squashed together by the moving ambulance. This causes more vibrations to reach your ear per second.

Answer:

KE = F * S     initial kinetic energy will expended in stopping object

1/2 M V^2 = F * S

S = 1/2 * 50 * 35^2 / 800 = 38.3 m      stopping distance

If you need to know the stopping time involved -

(V2 - V1) = a t     where the change in velocity is 35 m/s

a = F / M = 800 / 50 = 16 m/s^2      deceleration of mass

t = 35 / 16 = 2.2 sec

The speed of the target with the bullet lodged in it is 5.6 m/s.

This is the rate of change of distance.

To calculate the speed of the target and the bullet lodged, we use the formula below.

The magnitude of the induced current is, (I=9 /R). The principal of ohm's law is employed in the given problem.

Emf is the production of a potential difference in a coil as a result of changes in the magnetic flux passing through it.

When the flux coupling with a conductor or coil changes, electromotive force, or EMF, is said to be induced.

The given data in the problem is;

B is the magnetic field,= 2t^2−3.

t(time)=3 sec

The induced EMF is found as;

[tex]\rm E= \frac{d \phi}{dt} \\\\\ \rm E= \frac{d(2t^2-3)}{dt} \\\\\ E=4t-3\\\\\ t= 3 sec \\\\ E=12-3 \\\\\ E= 9 \ V[/tex]

From ohm's law;

E=IR

I=E/R

I=9 /R

Answer:

As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by "thin air." Thin air exerts less pressure than air at a lower altitude

Answer:    Advantages of following the soft path, the argument here is alternative sources of power such as hydropower, geothermal energy , wind energy , and photovoltaic cells must be developed. This provides a alternative source to remain in a healthy environment and also function as the society we currently live in using the hard path.  Disadvantages of following the hard path result with future generations fearing over the irreversible damage of climate change and the damage done to our atmosphere. The hard path argue that we should continue to operate in the future as we have in the past, except more efficiently. This is close to impossible and will only continue the negative effects the hard path( the path we have been following) results in. The major shift determines the outcome of this world, the futures worries or reliefs and ultimately the survival of humans.

NaCl is an electrolyte.

Answer:

Pressure of .2 m^3 of bricks:

Pb = ρ g H = 1.8 ρw * 9.80 m/s^2 * .20 m = 1800  * 9.8 * .2 = 3530 Pascals

ρb = 1.8 ρw = 1.8    since the density of bricks is 1.8 that of water

Pw = 1 * 9.8 * 1000 * .2 = 1960 Pascals

W = P * A   pressure * Area = Force

Pnet = 1570 Pascals - pressure due to bricks under water

Answer:

It's a kinematic equation.

Explanation:

x displacement = (velocity_final * time) - (0.5 * acceleration * time * time)

You should be given a value, context(word problem), or diagram.

If you're deriving for a term just isolate the term.

If you're asking why the -(0.5 * acceleration * time * time) is negative instead of positive, would need context.

The cart's acceleration to the right after the mass is released  is determined as 7.54 m/s².

The acceleration of the cart is determined from the net force acting on the mass-cart system.

Upward force = Downward force

ma = mg

13a = 10(9.8)

13a = 98

a = 98/13

a = 7.54 m/s²

Thus, the cart's acceleration to the right after the mass is released  is determined as 7.54 m/s².

Answer:

3.33 m/s west

Explanation:

East is the positive direction.

400kg*20m/s + 800kg*-15m/s =(400kg+800kg)*v

-4000kgm/s=1200kg*v

v=-3.33

400kg*20m/s + 800kg*-15m/s =(400kg+800kg)*v. -4000kgm/s=1200kg*v and v=-3.33.

Collision, which is also known as impact, is the abrupt, powerful coming together in close proximity of two bodies, such as two pool cues, a golf club and a ball, a hammer and a nail, two railroad cars when linked, or a falling object and a floor.

Two factors—the force and the amount of time the items are in contact—affect the outcome of impact in addition to the characteristics of the two objects' materials.

A hard steel ball dropped on a steel plate will typically rebound to almost the same location from whence it was dropped, while a putty or lead ball would not.

Therefore, 400kg*20m/s + 800kg*-15m/s =(400kg+800kg)*v. -4000kgm/s=1200kg*v and v=-3.33.

Given the value of force applied in the given duration of time, the impulse or change in momentum caused by the net force is 720kgm/s.

An impulse is simply a concept that involves the change in the momentum of an object when force is introduced for a period of time.

It is expressed as;

ΔP or Change in Momentum = F × t

Where F is force applied and t is the elapsed time.

Given the data in the question;

ΔP = F × t

ΔP = 240kgm/s² × 3s
