In a trial, an expert witness uses the conservation of momentum to demonstrate which initial velocities would give the final states that occurred in the accident. Can using the conservation of momentum be justified in this case? Yes, because momentum is conserved in all collisions. No, momentum is only conserved in elastic collisions which this is not. No, energy is always conserved, but momentum is only sometimes conserved. Yes, because momentum is conserved in inelastic collisions which all car accidents are.​

Answers

Answer 1

Answer:

Yes, because momentum is conserved in all inelastic collisions which all car accidents are

Step-by-step explanation:

What is law of conservation of momentum?

It states that In a equilibrium the initial momentum is equal to to the final momentum of the body

Or

[tex]\\ \sf\longmapsto \Delta P=P[/tex]

Answer 2

Answer:

• Yes, because momentum is conserved in all collisions.

Step-by-step explanation:

→ Elastic collision, inelastic collision and perfectly inelastic collision, linear momentum is conserved assuming no external forces acting on the system.

In elastic collision

[tex] \dashrightarrow \: { \tt{m _{1}u _{1} + m _{2} u_{2} = m_{1}v_{1} + m_{2}v_{2}}} \\ [/tex]

In inelastic collision

[tex] \dashrightarrow \: { \tt{m_{1}u_{1} + m_{2}u_{2} = (m_{1} + m_{2})v}}[/tex]

A. The left end goes up and the right end goes down.
B. Both ends

down.
C. Both ends go up.
D. The left end goes down and the right end goes up.

Answers

Answer:

Ok, so it seems

erm

ok, even and odd

it is an odd one because the power is odd (3rd degree)

so then the ends go in different directions

and since leading coefient (5 in the 5x^3) is positive, it goes from bottom left to top right

so

A is false

B is false

C and D are true

answer is C and D

Answers

Answer:

[tex]\frac{5}{12}[/tex]

Step-by-step explanation:

The given problem is a subtraction problem between fractions. The first step in a problem like this is to convert both fractions to a common denominator. In other words, multiply both the numerator and denominator of a fraction by the same value such that the denominator of one of the fractions is the same as the other fraction. The numerator of a fraction is the value over the fraction bar, whereas the denominator is the value under it. Multiplying any fraction by a number over itself is the same as multiplying it by one, thus, the equation will remain true, and be equivalent to the original expression.

[tex]\frac{13}{12}-\frac{2}{3}[/tex]

Convert to a common denominator,

[tex]\frac{13}{12}-(\frac{2}{3}*\frac{4}{4})[/tex]

[tex]\frac{13}{12}-\frac{8}{12}[/tex]

Now perform the subtraction, subtract one numerator from the other, remember, do no perfrom any more operations with the denominators,

Answer:

  13.  (A, b, C) = (30.66°, 91.042, 25.34°)

  14.  insufficient information

Step-by-step explanation:

13. The Law of Cosines can help you find the side opposite the given angle. Then that can be used with the Law of Sines to find the other angles.

  b = √(a² +c² -2ac·cos(B)) = √(56² +47² -2(56)(47)cos(124°)) ≈ √8288.59

  b ≈ 91.042

__

  A = arcsin(a/b·sin(B)) ≈ arcsin(56/91.042·sin(124°)) ≈ 30.66°

  C = 180° -124° -30.66° = 25.34°

The missing dimensions are (A, b, C) = (30.66°, 91.042, 25.34°).

Answer:

Step-by-step explanation:

its D because 400 divided by 8 is 50

[tex]\boldsymbol{4}[/tex] is closest to the radius, in inches, of the cylinder.

So, option A. is correct.

Volume of cylinder

Height of a cylinder [tex](h)=8[/tex] inches

Volume of a cylinder[tex]=400[/tex] cubic inches

Let [tex]r[/tex] denotes radius of a cylinder.

Volume of a cylinder [tex]=\pi r^2 h[/tex]

[tex]400=\frac{22}{7}r^2 (8)[/tex]
