Answer:
35 km/hr
Explanation:
Average speed = (total of the speed)/(the sets of speeds given)
Direction does not matter in this instance since speed is only magnitude,
Average speed = (30 + 40)/2
Average speed = 70 ÷ 2
= 35 km/hr
Answer:
11
Explanation:
1. You are going to be rounding down.
2. change the metric ton to kg.
1.000 * 10^3 kg = 1000 kg
1000 / 87 = 11.49 = 11 people
B Ik it all just know who they’ll you
Answer:
The non-relativistic kinetic energy of a proton is
The relativistic kinetic energy of a proton is
Explanation:
Given that,
Mass of proton
Speed
We need to calculate the kinetic energy for non relativistic
Using formula of kinetic energy
Put the value into the formula
We need to calculate the kinetic energy for relativistic
Using formula of kinetic energy
Hence, The non-relativistic kinetic energy of a proton is
The relativistic kinetic energy of a proton is
Answer:
9.8m/s²
Explanation:
The acceleration of the ball thrown after leaving my hand is 9.8m/s². This will be the acceleration due to gravity on the body.
- Acceleration due to gravity is caused by the pull of the earth on a massive object.
- The value of this acceleration is 9.8m/s².
- As the ball nears the surface, it comes near zero.
