The answer would be C. 80%
Put 160 over 200 and find the GCF
160/200÷40=4/5=80%
Answer:
Explanation:
We can use Newton's Second Law to solve this exercise, which states that an object of mass m subjected by a force of magnitude F will experiment an acceleration given by the formula F=ma. I our case we want the acceleration, so we can write a=F/m, and use the values given:
a=F/m=(1000N)/(1000kg)=1m/s2.
Answer:
10.53m/s²
Explanation:
Centripetal acceleration is the acceleration of an object about a circle. The formula for calculating centripetal acceleration is expressed by:
v is the velocity of the car = 24.5m/s
r is the radius of the track = 57.0m
Substitute the given values into the formula:
Hence the centripetal acceleration of the race car is 10.53m/s²
Answer: 384,300,000 m
Explanation:
Speed is mathematically expressed as:
Where:
is the speed of light
is the distance traveled
since is the time it takes to the pulse to go the moon and return.
Finding :
