Answer: D(t)= 50(4/5)^t
Explanation: If 1/5 of the temperature difference is lost each minute, that means 4/5 of the difference remains each minute. So each minute, the temperature difference is multiplied by a factor of 4/5 (or 0.8).
If we start with the initial temperature difference, 50° Celsius, and keep multiplying by 4/5, this function gives us the temperature difference t minutes after the cake was put in the cooler.
"Decimeter" is a unit of length or distance, whereas "milliliter" is
a unit of volume. They measure different quantities, and have
different physical dimensions. Neither one can be converted to
the other one.
If it were possible to convert volume to length or distance, you
(or someone with a better handle on his math and physics) could
figure out how many inches of milk you poured on your cereal.
Answer:
35.2 ps
Explanation:
Hello!
A US short ton is equal to 2 000 pounds, therefore:
2.25 tons = 4500 pounds
Now lets convert the area of each tire footprint:
1 cm = 0.393701 in
12.5 cm = 4.92126 in
16.5 cm = 6.49607 in
Therefore, the area of the footprint is: 31.9688 in^2
Then, the pressure exerted by the car is given by the weigth devided by the total area, that is 4 times the area of the footprint :
4500 /(4 * 31.9688) psi = 35.1906 psi
Rounding to the first tenth
35.2 psi
The force of 30 Newtons has. Its magnitude is 30 Newtons.
Answer:
is the distance from the target before which the pilot must release the canister.
Explanation:
Given:
- height of the plane,
- horizontal speed of plane,
<u>Time taken by the canister to hit the ground:</u>
using equation of motion
where:
initial vertical velocity of the canister = 0 (since the the object is dropped from a horizontally moving plane)
time taken to hit the ground
<u>Now the horizontal distance travelled by the canister after dropping:</u>
is the distance from the target before which the pilot must release the canister.
