<span>m^(- 5) = 1/35 → you know that: x^(- a) = 1/x^(+ a) = 1/x^a
1/m^5 = 1/35 → you take the inverse
m^5 = 35
[m^5]^(1/5) = 35^(1/5) → recall: (x^a)^b = x^(ab)
m^[5 * (1/5)] = 35^(1/5)
m^[1)] = 35^(1/5)
m = 35^(1/5)
The scientific notation is a number between 1 and 9 with few numbers after coma (point) completed by a power 10.
= [1.4 * 10^(3)] * [2.5 * 10^(- 6)] → you remove the brackets
= 1.4 * 10^(3) * 2.5 * 10^(- 6) → you order
= 1.4 * 2.5 * 10^(3) * 10^(- 6) → you make the multiplication
= 3.5 * 10^(3) * 10^(- 6) → recall: (x^a) * (x^b) = x^(a + b)
= 3.5 * 10^(3 - 6)
= 3.5 * 10^(- 3) ← answer C</span><span>

Answer:
496.7 K
Explanation:
The efficiency of a Carnot engine is given by the equation:
where:
is the temperature of the hot reservoir
is the temperature of the cold reservoir
For the engine in the problem, we know that
is the efficiency
is the temperature of the cold reservoir
Solving for , we find:
A paper clip is a example of a thing that has a mass of one gram.
Explanation:
It is given that,
When a high-energy proton or pion traveling near the speed of light collides with a nucleus,
Speed of light,
Let t is the time interval required for the strong interaction to occur. The speed is given by :
So, the time interval required for the strong interaction to occur is . Hence, this is the required solution.
