Answer:

0.5 A

Explanation:

Applying,

V = IR.................. Equation 1

Where V = Voltage, I = current, R = Resistance.

make I the subject of the equation

I = V/R............... Equation 2

From the question,

Given: V = 75 V, R = 150 Ω

Substitute these values into equation 2

I = 75/150

I = 0.5 A.

Hence the cuurent through the resistor is 0.5 A

Block with m = 300 grams oscillates at the end of a linear spring with k = 6.5 N/m. (assume this is a top-down view and the bloc

masha68 [24]

Explanation:

Given that,

Mass of the block, m = 300 g = 0.3 kg

Linear spring constant, k = 6.5 N/m

(a) Let T is the period of the block's motion. It is given by :

$T=\dfrac{2\pi}{\omega}$

where

$\omega=\sqrt{\dfrac{k}{m}}$ = angular frequency

Also, $\omega=\sqrt{\dfrac{k}{m}}$

$T=\dfrac{2\pi}{\sqrt{\dfrac{k}{m}}}$

$T=\dfrac{2\pi}{\sqrt{\dfrac{6.5}{0.3}}}$

T = 1.34 seconds

(b) The maximum acceleration of the block is, $a_{max}=2\ m/s^2$

The maximum acceleration is given by :

$a_{max}=\omega^2A$

A is the amplitude of the motion,

$A=\dfrac{a_{max}}{\omega^2}$

$A=\dfrac{a_{max}}{(\sqrt{\dfrac{k}{m}})^2}$

$A=\dfrac{ma_{max}}{k}$

$A=\dfrac{0.3\times 2}{6.5}$

A = 0.09 meters

Hence, this is the required solution.
