To figure out the answer, we need to use the formula for Work
The formula for Work is: W = F x D, or Work = Force times Distance.
We have our force and our distance, so we can answer this.
Our force is 150N, and our distance is 10 ft.
Since our formula is Force x Distance, let's multiply them.
150 x 10 = 1500.
Our work done is 1500J.
Your answer is 1500 foot pounds.
I hope this helps!
The momentum of each cart is given by:
where
m is the mass of the cart
v is its velocity (at the bottom of the ramp)
To answer the problem, let's calculate the momentum of each of the 4 carts:
1)
2)
3)
4)
Therefore, the cart with greatest momentum is cart 3, so the right answer is
<span>- trial 3, because this trial has a large mass and a large velocity</span>
Carson’s <span>“Silent Spring” influenced the
environmental movement </span>as it presents a view of nature compromised by synthetic pesticides,
especially DDT. The pesticides not only kill bugs but also threaten bird and
fish populations, and eventually sicken children. Much of the data and case
studies that Carson drew from weren’t new but she was the first to consolidate
them all for the general public and to draw blunt conclusions. This book was so
revolutionary that by the end of the twentieth century, it took its place on
lists of the best books of the century or even of all time.
Answer:
Explanation:
This question seek to test the difference between a scalar and a vector quantity. A scalar quantity is a quantity that has just magnitude but no direction while a vector quantity is a quantity that has both magnitude and direction. Example of a scalar quantity is speed while example of a vector quantity is velocity.
Hence, it can be that <u>speed has magnitude but no direction while velocity has both magnitude and direction</u>.
They both have the same formula which can be written as
speed = distance ÷ time
OR as
velocity = distance ÷ time
