Answer:
(3) 53°
Explanation:
We want to measure the angle that the rains form with the vertical wind shield, so we have to measure the angle relative to the vertical. This means that we can write the following equation
where
is the speed of the rain, which travels vertically
is the speed of the bus, which travels horizontally
Substituting, we find
Answer:
0.5 m.
Explanation:
From the question given above, the following data were obtained:
Force (F) = 5 N
Work done (W) = 2.5 J
Distance (s) =?
Workdone is simply defined as the product of force (F) and distance (s) moved in the direction of the force. Mathematically, it is expressed as:
Work done (W) = Force (F) × Distance (s)
W = F × s
With the above formula, we can obtain the distance to which the book has moved as follow:
Force (F) = 5 N
Work done (W) = 2.5 J
Distance (s) =?
W = F × s
2.5 = 5 × s
Divide both side by 5
s = 2.5/5
s = 0.5 m
Therefore, the book moved 0.5 m when the force was applied.
Well basically in physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time. This law means that energy can neither be created nor destroyed, it can only be transformed or transferred from one form to another.
Hope this helps (:
Answer:
It is A
Explanation:
At year six more land became avaliable this is the only way that the population could grow so fast and it is correct on edg.
Answer:
The maximum pressure is 10 V from across condenser.The highest charge mostly on condenser.
Vc = 10 x 1mf
= 10 ^ - 5C
The time it takes for the condenser to be 5 V different.
Thus we have, 0.69 x 10 ^ - 3 seconds.
