Answer:
Explanation:
By conservation of energy, loss in potential energy = gain in kinetic energy
mgh = 1/2mv^2
v^2 = 2gh
v = sqrt(2gh)
So the mass or density of snowball has no effect on its velocity/speed. The speed will stay the same.
Then things would turn bad and not good.
Answer:
None of these are correct
The value x = 35 is correct
Explanation:
<u><em>Step(i):</em></u>-
Given
We will apply logarithmic formula
log(a) + log (b) = log a b
logₓ a = b
⇒ a = xᵇ
<u><em>Step(ii)</em></u>:-
⇒ 2 ( x + 15 ) = 10²
⇒ 2 x + 30 = 100
⇒ 2 x = 70
⇒ x = 35
<u><em>Final answer:-</em></u>
x = 35
<u><em>Verification:-</em></u>
<u><em></em></u>
log x ⁿ = n log x
2 log¹⁰ ₁₀ = 2
2 = 2 ( log¹⁰ ₁₀ = 1
Answer:
C. less power than larger cars.
Explanation:
Generally a smaller car would have less room for larger and more powerful equipment. However, this may not be the case in today's standards, which calls for powerful and smaller. But usually the larger it is, the more powerful, if current standard "larger power" is the same as the current for "smaller power".
