Answer:
increases by a factor of 
Explanation:
First we need to find the initial velocity for it to stop at the distance 2d using the following equation of motion:
where v = 0 m/s is the final velocity of the package when it stops, 
is the initial velocity of the package when it, a is the deceleration, and 
is the distance traveled.
So the equation above can be simplified and plug in Δs = d, 
for the 1st case
(1)
For the 2nd scenario where the ramp is changed and distance becomes 2d, 
(2)
let equation (2) divided by (1) we have:
So the initial speed increases by . If the deceleration a stays the same and time is the ratio of speed over acceleration a
The time would increase by a factor of
Answer:
Mechanical weathering breaks rocks into smaller pieces without changing their composition. ... Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface. Water, carbon dioxide, and oxygen are important agents of chemical weathering.

Answer:
44.492 kg
Explanation:
Convert pounds to kilograms.
1 lb = 0.454 kg
98 lb * 0.454 kg =44.492 kg
That is incorrect friction is able to stop some thing or slow it down so it is the opposite way around. Please put bainliest!

Answer:
Thickness is 217 nm
Explanation:
For a thin film, constructive and destructive interference each has its own effects. Here constructive interference causes the light to be strongly reflected. The thickness can be determined from
here n is refractive index 1.38, m=1 , 
=0, 
=600 nm
