Answer:
155 118 in
Explanation:
3.94 km * 1000 m / km * 39.37 in / m = 155 118 in
I don’t speak this wish i could help!
Answer:
90 m/s
8100 m
Explanation:
Given:
v₀ = 0 m/s
a = 0.5 m/s²
t = 3 min = 180 s
Find: v and Δx
v = at + v₀
v = (0.5 m/s²) (180 s) + 0 m/s
v = 90 m/s
Δx = v₀ t + ½ at²
Δx = (0 m/s) (180 s) + ½ (0.5 m/s²) (180 s)²
Δx = 8100 m
Answer:
a) 3.9 x 10⁻⁵ kg
Explanation:
The amount of mass required to produce the energy can be given by Einstein's formula:
![E = mc^2\\\\m = \frac{E}{c^2}](https://tex.z-dn.net/?f=E%20%3D%20mc%5E2%5C%5C%5C%5Cm%20%3D%20%5Cfrac%7BE%7D%7Bc%5E2%7D)
where,
m = mass required = ?
E = Energy produced = 3.5 x 10¹² J
c = speed of light = 3 x 10⁸ m/s
Therefore,
![m = \frac{3.5\ x\ 10^{12}\ J}{(3\ x\ 10^8\ m/s)^2} \\\\m = 3.9\ x\ 10^{-5}\ kg](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B3.5%5C%20x%5C%2010%5E%7B12%7D%5C%20J%7D%7B%283%5C%20x%5C%2010%5E8%5C%20m%2Fs%29%5E2%7D%20%5C%5C%5C%5Cm%20%3D%203.9%5C%20x%5C%2010%5E%7B-5%7D%5C%20kg)
Hence, the correct option is:
<u>a) 3.9 x 10⁻⁵ kg</u>
Answer:
the answer is E-F
Explanation:
why is because the others are lines but E-F is curve
