Answer:
A. The bus has more kinetic energy than the car.
Explanation:
Kinetic energy is the amount energy possessed by the body when in motion. Kinetic is given by the formula;
K.E = 1/2mv²,
where m is the mass of the body and v is the velocity of the body.
Kinetic energy therefore depends on the mass and the velocity of the body. In this case, the passenger bus has more kinetic energy at constant speed than the car since it has a larger mass.
Answer:
f=ma
Explanation:
According to second law of motion Force is directly proportional to rate of change of momentum.
so F is directly proportional to
we know that momentum P= MV
so
thus we get F=ma.
Now we know that he is getting a raise by 9%.
So that means we have to find out what is 9% of $58,000.
we can do this by multiplying them.
But first we turn 9% into a decimal.
9% = 0.09
Lets multiply
0.09 x $58,700 = $5,283
So since this is a raise we have to add that 9% to our first value.
$58,700 + $5,283 = $63983
So Frank now earns in his new salary $63,983
Answer:
c. Tape measure.
Explanation:
Here in this case we have to measure the length of the object ( distance) so we need to use tape measure.
Tape measure is a device used to measure small distances. It consists of ribbon of clothes, plastic , fiber. glass or metal strip with linear measurement markings. rest all options do not measure length.
