How are electrical charges similar to magnets?
earnstyle [38]

Answer:

The two types of forces are related; a moving magnet can make electrical charges move, cause an electric current, and in turn cause magnetism. ... Objects that have the same charge, both positive or both negative, repel each other, and those with opposite charges attract each other.

The force of the pulley is 652 newtons. It accelerates at 53 m/s. How much does the object weigh. a 1230 grams b 1.230 gram c 12
RoseWind [281]

Answer:

d. 12.30 grams

Explanation:

Given the following data;

Force = 652 N

Acceleration = 53 m/s²

To find how much the object weigh, we would need to determine its mass;

Force = mass * acceleration

652 = mass * 53

Mass = 652/53

<em>Mass = 12.30 grams.</em>

<em>Therefore, the object weighs 12.30 grams. </em>

An airplane is traveling 25° west of north at 300 m/s when a wind with velocity 100 m/s directed 35° east of north begins to blo
hodyreva [135]

Answer:

The resultant velocity is 360.5 m/s  and direction 79° north of east.

Explanation:

Given that,

Velocity of airplane = 300 m/s

Velocity of wind = 100 m/s

Angle θ₁ = 25°

Angle θ₂ =35°

The horizontal velocity component

Using formula of velocity

v_{x}=v_{1}\cos\theta-v_{2}\cos\theta

Put the value into the formula

v_{x}=300\cos65-100\cos55

v_{x}=69.42\ m/s

The vertical velocity component

Using formula of velocity

v_{y}=v_{1}\sin\theta+v_{2}\sin\theta

Put the value into the formula

v_{y}=300\sin65+100\sin55

v_{y}=353.8\ m/s

We need to calculate the resultant velocity

Using formula of resultant velocity

v=\sqrt{v_{x}^2+v_{y}^2}

Put the value into the formula

v=\sqrt{69.42^2+353.8^2}

v=360.5\ m/s

We need to calculate the direction of the resultant velocity

Using formula of direction

\tan\theta=\dfrac{v_{y}}{v_{x}}

Put the value into the formula

\theta=\tan^{-1}(\dfrac{353.8}{69.42})

\theta=79^{\circ}

Hence, The resultant velocity is 360.5 m/s  and direction 79° north of east.
