Below the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2,900 km thick. The mantle, which contains more iron, magnesium, and calcium than the crust, is hotter and denser because temperature and pressure inside the Earth increase with depth.

Answer:
A.
Explanation:
momentum depends on weight and speed
Answer:
This is a very straightforward problem, and not too difficult to do in your head. If we have two nearly equal resistances, the series resistance (Rs) is twice the average value (midpoint between the two) and the parallel resistance Rp) is approximately equal to half the midpoint value. So a rough initial guess might be 12 and 13 ohms, where Rs is 25 ohms but Rp is approximately 6.25 ohms. Since Rp needs to be lower, we can play around with resistor values. Here’s an easy shortcut:
Let’s start with the equation for two parallel resistors:
Rp = (R1 * R2)/(R1 + R2)
Since Rs = R1 + R2,
Rp = (R1 * R2)/Rs.
We can rewrite this as
Rp * Rs = R1 * R2
Plugging in our numbers (Rp = 6, Rs = 25), we see that R1 + R2 = 150. What two numbers in the vicinity of 12 and 13 have the product of 150 and a sum of 25? Immediately 10 and 15 come to mind! Easy enough!
We Know, Velocity = Distance / Time
Here, Distance = 1000 miles
Time = 2 weeks = 14*24 Hours [ 1 week = 7 days & 1 day = 24 hours ]
Time = 336 Hours
Now, substitute the values,
Velocity = 1000/336 = 2.976 miles/hour
So, your final answer is 2.976 miles/hour

Answer:
The answer is transferred. So your answer will be: When you do work on an object some of the energy is transferred to that object.
