Elevator mass 750kg tension on cable 8950n what is the net force action on the elevator

For a cosine function with amplitude A=0.75 and period T=10, what is y(4)?

mixer [17]

2π/T = 2π/10 = π/5

y(x) = A sin (wx) = 0.75 sin (πx/5)

y(4) = 0.75 sin (4π/5) = 0.4408389392... ≈ 0.441

lightning and thunder both occur at the same time why do you see the Lightning before you hear the thunder

denis23 [38]

Because the light from it travels to you about 874 thousand times
as fast as the sound does, so the hearing part falls behind the seeing
part.

A solenoid of length 5.0 cm has a cross sectional area of 1.0 cm2 and has 300 uniformly spaced turns. The solenoid is wrapped in

OleMash [197]

The calculated mutual inductance is 8.544 x 10⁻⁵ H.

Two coils have a mutual inductance of 1 henry when emf of 1 volt is induced in coil 1 and when the current flowing through coil 2 is changing at the rate of one ampere per second.

Length of the solenoid= 5.0 cm

Area of cross-section=1.0 cm²

no of spaced turns=300 turns

turns of insulated wire=180 turns

Mutual inductance (M) = μ₀μr N1N2 A/ L

=(4xπx 10⁻⁷) x (6.3 x 10⁻³) x 300 x 180 x 1/ 5

=79.12 x 10⁻¹⁰ x 54000 / 5

=8.544 x 10⁻⁵ H

hence, the mutual inductance is 8.544 x 10⁻⁵ H.

Find the average net force.

Lerok [7]

Answer:

<h2>given</h2>

mass= 3.5 kg

distance covered= 0.4m

inital speed = 1.5 m/sec

final speed = 0 m/sec

net force

<h2>solution</h2>

formula for force :

$\fbox{f = m.a}$

In order to find the force we need to find the acceleration.

According to third equation of Kinematics-

$\bold{ {v}^{2} = {u}^{2} + 2as}$

where,

v= final velocity

u=inital Velocity

a=Acceleration

s=Distance covered

put the value in the above equation

0= (1.5)²+ 2a x 0.4

-2.25= 0.8a

a = -2.25/0.8

a= - 2.8125 m/sec²

now put the value 0f accleration in formula of force

F = 3.5 x - 2.8125

F= -9.84375 N
