This question seems to really be incomplete. You must include the options but fortunately I have already encountered this problem.
Here are the choices:

<span>A. have a different frequency than the resultant wave.
B. be in phase with each other.
C. be traveling in the opposite direction of the resultant wave.
D. have a different wavelength than the resultant wave

The correct answer is letter B. be in phase with each other</span>

Which of these statements is true about endothermic reactions, but not about exothermic reactions?
sashaice [31]
I think the correct answer from the choices listed above is the second option. For endothermic reactions, the reactants have less energy than the products. Which would mean that energy should be added to the reaction for it to proceed. Hope this answers the question.

A 6.0-kg object, initially at rest in free space, "explodes" into three segments of equal mass. Two of these segments are observ
sladkih [1.3K]

Answer:

Q = 2000 J

Explanation:

As we know that the 6 kg object was at rest initially

So here since net force on the system is zero

so the momentum of the system will always remains conserved

so we can say

0 = P_1 + P_2 + P_3

now we know that

P_1 = P_2 = P

and the angle between the two objects is 60 degree

so we can say

\vec P_1 + \vec P_2 = \sqrt{P_1^2 + P_2^2 + 2P_1 P_2cos60}

\vec P_1 + \vec P_2 = \sqrt{P^2 + P^2 + 2P^2(0.5)} = \sqrt3 P

now we can say that the speed of the third mass will be

v_3 = \sqrt 3 (20) m/s

now the total kinetic energy released in this system is given as

Q = \frac{1}{2}mv_1^2 + \frac{1}{2}mv_2^2 + \frac{1}{2}mv_3^2

Q = \frac{1}{2}(2)(20^2) + \frac{1}{2}(2)(20^2) + \frac{1}{2}(2)(20\sqrt3)^2

Q = 2000 J

In which of the following situations would there be initial energy in the system?
pshichka [43]

Answer:

A spring is compressed and held at compression by a person before releasing it

Explanation:

All the other answers are showing things that are at rest and have no energy starting nor going through them. This answer show how the energy is starting and being released.
