Answer:

amplitude

Explanation:

The maximum distance from the mean position or the equilibrium position on its either side of an oscillating body is called its amplitude.

The appropriate response is amplitude. A measure of its change over a solitary period. There are different meanings of plentifulness, which are all elements of the extent of the distinction between the variable's outrageous qualities. In more seasoned writings, the stage is now and again called the adequacy.

A car of mass 775 kg traveling at a velocity of 30 m/s in the positive x-direction crashes into the rear of a truck of mass 1,47

Thepotemich [5.8K]

Answer:

velocity of the car is 7.3516 m/s

Explanation:

M1v1a + m2v1b = m1v2a + m2v2b

775*30 + 1475*0 = 775*v2a+1475*11.9

Let v2a be x

23250 + 0 = 775x + 17552.5

775x = 23250-17552.5

775x = 5697.5

X = 7.3516 m/s

Suppose you have a 34.9 m length of copper wire. If the wire is wrapped into a solenoid 0.240 m long and having a radius of 0.05

Nadusha1986 [10]

Answer:

the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.

Explanation:

Given;

length of the wire, = 34.9 m

length of solenoid, L = 0.24 m

radius of the solenoid, r = 0.051 m

current in the solenoid, I = 11.0 A

The number of turns of the wire is calculated as follow;

$N = \frac{34.9}{2\pi \times 0.051} = 109 \ turns$

The strength of the magnetic field inside the solenoid is calculated as follows;

$B = \mu_0 (\frac{N}{L} )I\\\\B = 4\pi \times 10^{-7} \times (\frac{109}{0.24} )\times 11.0 \\\\B = 6.278 \times 10^{-3} \ T$

Therefore, the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.

What is an inertial reference frame?

Gennadij [26K]

<h2>Answer: A system in which Newton's Laws are fulfilled</h2>

An inertial reference system is a reference system in which the principle of inertia is fulfilled, which is one of Newton's laws:

<em>"For a body to have acceleration, an external force must act on it" </em>

In addition, the other Newton's laws of movement are fulfilled.

Therefore, the variation of the linear momentum of the system is equal to the actual forces on the system.

A refrigerator has a coefficient of performance equal to 4.00. The refrigerator takes in 110 J of energy from a cold reservoir i

Helga [31]

Answer:

The correct answer is:

(a) 27.5 Joules

(b) 141.5 Joules

Explanation:

Given:

Energy,

$Q_c = 110 \ J$

Coefficient of performance refrigerator,

$Cop(refrig)=4$

(a)

As we know,

⇒ $Cop(refrig) = \frac{Q_c}{Work}$

or,

⇒ $Work=\frac{Q_c}{Cop(refrig)}$

$=\frac{110}{4}$

$=27.5 \ Joules$

(b)

⇒ $Heat \ expelled = Heat \ removed +Work \ done$

or,

⇒ $Q_h = Q_c+Work$

$=114+27.5$

$=141.5 \ Joules$
