Answer:
are you college ?????????
Answer:
Below
Explanation:
To calculate the time it took for the cyclist to finish their race, you can you this equation :
time = displacement / velocity
Plug in your values....
time = (100 mi) / (22 mi/h)
= 4.54545454.... hours
As for sig figs in this question you would need to round this answer to 1 sig fig because 100 only has 1 sig fig. (you round to the lowest # of sig figs in the question)
= 5 hours
It took the cyclist 5 hours to complete their race
Hope this helps! Best of luck <3
Answer:
The thrust of the jet engine is 4188.81 N.
Explanation:
Given that,
Speed = 260 m/s
Rate in air= 53.3 kg/s
Rate of fuel = 3.63 kg/s
Relative speed = 317 m/s
We need to calculate the rate of mass change in the rocket
Using formula of rate of mass
Put the value into the formula
We need to calculate the thrust of the jet engine
Using formula of thrust
Put the value into the formula
Hence, The thrust of the jet engine is 4188.81 N.
Answer:
60 kg
Explanation:
The man's weight is equal to the weight of the water he displaces.
mg = ρVg
m = ρV
m = (1000 kg/m³) (3 m × 2 m × 0.01 m)
m = 60 kg
The man's mass is 60 kg.
Answer
a) Draw an upward force from the bottom to indicate upthrust
b) Upthrust is an upward force acting on an object floating on a liquid... hence there is an upward force acting on the iceberg which causes it to float.
c) Unfortunately I don't know the answer.
