Answer:
A. There are multiple paths that electrons can take through the circuit, and it is possible for the electron to pass through one circuit component but not another.
Explanation:
Parallel arrangement of components in an electric circuit puts different parts of the circuit on different branches. In a parallel connection, there are multiple paths for the electrons to take, and it is possible for electrons to pass through on circuit component without going through another. This is the reason why If there is a break in one branch of the circuit, electrons can still flow in other branches, and the same reason why one bulb going off in your home does prevent the other components in your home from coming on (your home is wired in a parallel electric circuit).

= Breaking stress of bone = 150 MPa
= Outer diameter = 3.6 cm
= Inner diameter = 2.3 cm
Area of the bone is assumed to be a hollow cylinder
Stress is given by
The maximum weight the person can lift without breaking his legs is 249003822308.05008 N
Answer:
0.80 m
Explanation:
Neglecting friction, the total mechanical energy of the pendulum is constant.
E = K + U where K = kinetic energy and U = potential energy.
At its release point of 0.80 m, the pendulum bob has a mechanical energy which is equal to its potential energy, since, its initial kinetic energy is zero. By the time the bob swings to the other end, it has a mechanical energy equal to it initial potential energy since total energy is conserved.
Neglecting friction, the pendulum bob would swing back to its original height of 0.80 m since the total mechanical energy is conserved and at its highest point, it is purely potential energy.
So, the height the pendulum bob swings to after release from a height of 0.80 m neglecting fiction is 0.80 m.
Answer:
22.74 m/s
Explanation:
u= 5.0
a= 2.4
t= 7.39
Therefore the final velocity can be calculated as follows
v = u + at
v= 5 + 2.4(7.39)
v= 5 + 17.736
v= 22.74 m/s
Hence the final velocity of the object is 22.74 m/s
Answer:
you can solve kinetic energy problem by using, Ke=1/2MV² where m is mass and v is velocity
