Likurg_2 [28]

Answer:

Magnetic force, $F=1.12\times 10^{-13}\ N$

Explanation:

It is given that,

Velocity of proton, $v=1.8\times 10^6\ m/s$

Angle between velocity and the magnetic field, θ = 53°

Magnetic field, B = 0.49 T

The mass of proton, $m=1.672\times 10^{-27}\ kg$

The charge on proton, $q=1.6\times 10^{-19}\ C$

The magnitude of magnetic force is given by :

$F=qvB\ sin\theta$

$F=1.6\times 10^{-19}\ C\times 1.8\times 10^6\ m/s\times 0.49\ Tsin(53)$

$F=1.12\times 10^{-13}\ N$

So, the magnitude of the magnetic force on the proton is $1.12\times 10^{-13}\ N$ . Hence, this is the required solution.

A 75.0 kg sailor climbs a 28.3 m rope ladder at and angle of 45.0degrees with the mast. how much work did he do?

sladkih [1.3K]

W = m · g · h
h = 28.3 m · sin 45° = 28.3 m · 0.707 = 20 m
g = 9.8 m/s²
W = 75 kg · 9.8 m/s² · 20 m
Answer:
W = 14,700 J = 14.7 kJ

In the fabrication of an electrical extension cord, the manufacturer wants to reduce the overall resistance of the wires in the

Bezzdna [24]

Answer:

Option B is correct.

Explanation:

The resistance of a material or wire is represented by the formula below.

R=(ρL)/A

where

R is resistance of wire
ρ is the resistivity of the material
A is the cross sectional area of wire
L is length of wire

Resistance increases with increase in length and resistivity which means options C and D are wrong.

A=(π $d^{2}$ )/4

An increase in diameter will result in a proportional increase in area

From the resistance formula, an increase in area will cause a reduction in the resistance of the material.Thus increased diameter of wire will lower the resistance of wire. Option B is correct

Explain why the intensity of the light in a flashlight beam decreases as the flashlight moves farther away.

Karolina [17]

Ir=Initial Intensity/Area of spread=Io4πr2
Ir∝1r2

It is seen from this expression that intensity is inversely proportional to the square of the distance. As we move away from the light source the intensity decreases at the rate of square of the distance from the source.

Brightness being the perception of intensity. more the intensity more bright the object is perceived and vice versa.
