I think it may be c, 1.7 v. I work with electricity a lot.
The answer in the first space provided is realistic whereas
the second space provided is fantastic. The correct answer would be letter B.
In realistic, it has many views in which the frame is the
window on the world whereas fantastic depicts imagination or remotes from
reality.
Having said that,
mV + M0 = (m + M)v; where m = bullet mass, M = block mass, V = bullet velocity upon incoming, and v = the block and bullet velocity (ideal without losses) is the answer you are looking for. Thus, v = V(m/(m + M)) is what you want. m = Mb, M = Mw, and V = Vi.
Answer: D. 273
Explanation: Celsius temperatures can be negative while kelvin goes down to absolute zero and doesn’t go any lower, thus no negative numbers
0.078 times the orbital radius r of the earth around our sun is the exoplanet's orbital radius around its sun.
Answer: Option B
<u>Explanation:</u>
Given that planet is revolving around the earth so from the statement of centrifugal force, we know that any

The orbit’s period is given by,

Where,
= Earth’s period
= planet’s period
= sun’s mass
= earth’s radius
Now,

As, planet mass is equal to 0.7 times the sun mass, so

Taking the ratios of both equation, we get,





Given
and
