Speed =distance/time
speed =150km/7200s
speed =0.0208333 km/s
so your answer is 0.0208333
Answer:
If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration. ... Force is directly proportional to acceleration (force ~ acceleration) As force increases acceleration increases.
Answer:
Zirconium
Explanation:
The total amount of electrons is 40, meaning the element must be zirconium, given the atom is not a cation or anion.
Use inversenormal on a calculator and type in .1 , 70 , 10 . That percent is for A and will determine at what mark an A will be. Do the same for the rest of the grades but change the first argument in the calculation
Answer:
122.5 Joule, or 122.5 j
Explanation:
Given,
mass of the object (m) = 5 kg
velocity of the object (v) = 7 m/s
Kinetic energy = 
× m × v²
Applying the formula:
Kinetic energy = × 5 × 7²
⇒ × 5 × 7 × 7
⇒ 
⇒ 122.5 Joule, or 122.5 j
Kinetic energy is the energy that an object gains as the result of the motion. It also depends on the mass of the object and force with which the motion is applied. In the given question, the mass of the object is 5 kg and the force of the velocity by which it is moving is 7 m/s.
