Answer:
See the explanation below
Explanation:
This happens because the coffee was at rest, at the time when the car accelerates to move forward the container containing the coffee also accelerates in the same direction, the liquid when moving suddenly spills. The same will happen if the car slows down, any sudden movement changes will cause the coffee to spill, understood by sudden movements when it accelerates or slows down.
The law of conservation of energy states that in any reaction, energy cannot be created or destroyed.
In other words, energy has to be conserved in every reaction.
The force exerted on the car during this stop is 6975N
<u>Explanation:</u>
Given-
Mass, m = 930kg
Speed, s = 56km/hr = 56 X 5/18 m/s = 15m/s
Time, t = 2s
Force, F = ?
F = m X a
F = m X s/t
F = 930 X 15/2
F = 6975N
Therefore, the force exerted on the car during this stop is 6975N
Answer:
variations in great horned owl body size due to food supply can be acted on by natural selection.
Explanation:
Natural selection can help select great horned owl with smaller body size since it's an advantage in a place with smaller available food sources, compared to a bigger body size that will need more food. At first, birds with smaller body survive while those bigger ones die out, and the smaller birds pass on this genes to their offspring.
Answer:
variation in body size due to inherited traits can be acted on by natural selection
Explanation :
Variations in body size in body size due to inherited trait can be acted upon by natural selection by favoring the size that is best suited for the survival of the species. Those with these genes survive and pass it on to their offspring, while those with the unfavorable body size are wiped out.
Answer:
Time will be 5 sec
And maximum height will be 1200 feet
Explanation:
We have given that initial velocity of the object u = 160 ft/sec'
Function of height 
Take derivative of the distance
We know that first derivative of distance is velocity
So 
At maximum height we know that velocity is zero
So 
t = 5 sec
So it will take 5 sec to reach maximum height
Now maximum height will occur at t = 5 sec
So maximum height =
