Answer:
(a)
(b) It won't hit
(c) 110 m
Explanation:
(a) the car velocity is the initial velocity (at rest so 0) plus product of acceleration and time t1
(b) The velocity of the car before the driver begins braking is
The driver brakes hard and come to rest for t2 = 5s. This means the deceleration of the driver during braking process is
We can use the following equation of motion to calculate how far the car has travel since braking to stop
Also the distance from start to where the driver starts braking is
So the total distance from rest to stop is 352 + 88 = 440 m < 550 m so the car won't hit the limb
(c) The distance from the limb to where the car stops is 550 - 440 = 110 m
Answer:
Though nepalgunj and taplegunj lie at the same latitude(28 degree) they greatly vary In climate..
This is a bad hypothesis because it's a statement. It is a description of what occurs, not a question that you will experiment upon to find an answer whether or not something will or will not be true.
<span>A differences in the warmth, or moisture level as well as neighbouring areas of pressure in </span>air cause air<span> to circulate. in the earth's atmosphere.</span>
The half-life is simply the amount of time it takes for half of the isotope to decay into something else.
<span>After 1 half-life, half of the original sample remains. After a second half-life, half of that part remains or 1/4 of the original....after 3 half-lives, 1/8 remains and so on. </span>
<span>In your example, ut started with 8 billion atoms. After one half-life, there was 4 billion. After a second half-life, there was 2 billion and after 3, one billion remain.</span>
