Displacement vectors of 10 m west and 14 m west make a resultant vector that is ?

goldenfox [79]

Resultant vector= 24 m west.

Explanation:

resultant vector= r1+ r2 when the two vectors are in same direction

r1=10m west

r2= 14 m west

so resultant displacement= 10 + 14

resultant displacement= 24 m west

One hundred turns of (insulated) copper wire are wrapped around a wooden cylindrical core of cross-sectional area 5.87 × 10-3 m2

Grace [21]

Answer:

The amount of charge that flow through a point is $\Delta q = 0.126 \ C$

Explanation:

From the question we are told that

The number of turns is $N = 100$

The area is $A = 5.87 *10^{-3} m^2$

The total resistance is $R = 14.9 \ \Omega$

The magnetic field in first direction is $B_1 = 1.93 \ T$

The magnetic field in second direction is $B_2 = -1.93 \ T$

The change in magnetic field is evaluated as

$\Delta B = B_1 - B_2$

substituting values

$\Delta B = 1.93 - [- 1.93]$

$\Delta B =3.2 \ T$

The induced emf due to the change is mathematically evaluated as

$e = NA \frac{\Delta B }{\Delta t }$

This can also be mathematically represented as

$e = IR$

Where I can be mathematically represented as

$I = \frac{\Delta q }{\Delta t}$

$e = \frac{\Delta q}{\Delta t } R$

Now

$\frac{\Delta q}{\Delta t } R = NA \frac{\Delta B }{\Delta t }$

=> $\Delta q = \frac{N A (\Delta B)}{R}$

substituting values

$\Delta q = \frac{100 * 5.87 *10^{-3} (3.2}{14.9}$

$\Delta q = 0.126 \ C$

#2 A car accelerates from rest at 4 m/s^2. What is the velocity of the car after 4 second?

solmaris [256]

You use the equation Velocity = Acceleration X Time. 4x4=16m/s.

The car travels 18m in 3 seconds.

An elevator is moving is an upwards

Minchanka [31]

Answer:

The elevator's free-body diagram has three forces, the force of gravity, a downward normal force from you, and an upward force from the tension in the cable holding the elevator. The combined system of you + elevator has two forces, a combined force of gravity and the tension in the cable.
