The velocity of the mass after 9 second is 88 m/s
Answer:
The correct option is (d).
Explanation:
- The energy a particle has because of its charge and its position relative to another particle is called thermal energy.
- It is the energy that comes from heat. This is generated by the movement of the particles in an object.
- Thermal energy is the energy an object or system has due to the movement of particles within.
Hence, the correct option is (d).
According to Newton's 3rd law, there will be equal and opposite force on the astronaut which is -6048 N
<h3>
What does Newton's third law say ?</h3>
The law state that in every action, there will be equal and opposite reaction.
Given that a rocket takes off from Earth's surface, accelerating straight up at 69.2 m/s2. We are to calculate the normal force (in N) acting on an astronaut of mass 87.4 kg, including his space suit.
Let us first calculate the force involved in the acceleration of the rocket by using the formula
F = ma
Where mass m = 87.4 kg, acceleration a = 69.2 m/s2
Substitute the two parameters into the formula
F = 87.4 x 69.2
F = 6048.08 N
According to the Newton's 3rd law, there will be equal and opposite force on the astronaut.
Therefore, the normal force acting on the astronaut is -6048 N approximately

A=m/s^2(meter per second square)
Work=joule
Answer: 9*10^15 N
Force=kqq/r^2
F=[(9*10^9)(1)(1)]/.001^2=9.0*10^15
