Answer:
h=15.27m
Explanation:
Since at maximum height the vertical velocity must be null it's better to use the formula:
![v_f^2=v_i^2+2ad](https://tex.z-dn.net/?f=v_f%5E2%3Dv_i%5E2%2B2ad)
We will use this formula for the vertical direction, choosing the upward direction as the positive one, so we have:
![0=v_i^2+2ah](https://tex.z-dn.net/?f=0%3Dv_i%5E2%2B2ah)
or
![h=-\frac{v_i^2}{2a}](https://tex.z-dn.net/?f=h%3D-%5Cfrac%7Bv_i%5E2%7D%7B2a%7D)
which for our values is:
![h=-\frac{(17.3m/s)^2}{2(-9.8m/s^2)}=15.27m](https://tex.z-dn.net/?f=h%3D-%5Cfrac%7B%2817.3m%2Fs%29%5E2%7D%7B2%28-9.8m%2Fs%5E2%29%7D%3D15.27m)
For a 50 kg person receives an absorbed dose of gamma radiation of 20 millirads, the total energy absorbed is mathematically given as
E=0.1457J
<h3>What is the total energy absorbed?</h3>
Generally, the equation for the total energy absorbed is mathematically given as
E=mass*gamma radiation
Therefore
E=50*20*19^{-3}
E=0.1457J
In conclusion, the total energy absorbed
E=0.1457J

Answer:
The magnetic force on a free moving charge depends on the velocity of the charge and the magnetic field, direction of the force is given by the right hand rule. While gravitational depends on the mass and distance of the moving particle and electric forces depends on the magnitude of the charge and distance of separation.
Explanation:
The magnetic force on a free moving charge depends on the velocity of the charge and the magnetic field and direction of the force is given by the right hand rule. While gravitational depends on the mass and distance of the moving particle and electric forces depends on the magnitude of the charge and distance of separation.
The magnetic force is given by the charge times the vector product of velocity and magnetic field. While gravitational force is given by the square of the particle mass divided by the square its distance of separation. Also electric forces is given by the square of the charge magnitude divided by the square its distance separation.
Answer:
yes
Explanation:
objects with constant velocity also have zero net external force. this means the forces on the object are balanced. this mean they are in equilibrium
Answer:
D: Increase the distance between the objects.
E: Decrease the mass of one of the objects.
