What's the difference between shunt and multiplier?​
vovikov84 [41]

Answer:

A Shunt is a passive element, usually resistive, that is used to bypass current around another element, like a meter, that is not able to handle the full current flow. ... A Multiplier is an active element that amplifies a voltage or current to enable a less sensitive device or circuit to make use of it.

A mass hangs on the end of a massless rope. The pendulum is held horizontal and released from rest. When the mass reaches the bo
drek231 [11]

Answer:

T = 37.5 N

Explanation:

As the pendulum reached to the lowest position then we will have

T - mg = \frac{mv^2}{L}

14.2 - m(9.81) = \frac{m(2.9^2)}{L}

now when it will reach to the height of the peg then its speed is given as

v_f^2 - v_i^2 = 2 a d

so we will have

v_f^2 - 2.9^2 = 2(-9.81)(\frac{L}{5})

v_f^2 = 2.9^2 - 3.924L

also we know that

2.9^2 - 0 = 2(9.81)(L)

L = 0.43 m

m = 0.48 kg

now we have speed of the pendulum when it reach the same height is given as

v_f^2 = 2.9^2 - (3.924(0.43)

v_f = 2.6 m/s

Now the tension in the string is given as

T = \frac{mv_f^2}{\frac{L}{5}}

T = \frac{0.48(2.6)^2}{\frac{0.43}{5}}

T = 37.5 N

Does an Atom of different elements have different number of protons
Murrr4er [49]
Atoms from two different elements may have the same number of neutrons, but never the same number of protons. The number of protons is unique to the element and represents the atomic number.
