Explain what an overloaded circuit is. How can you prevent having an overloaded circuit?

2 answers:

Overloaded curcuits are when gou have to many items running at one time (to much power on one cicuit) to prevent it simply turn some of the items on the circuit off or change a fuse to one that can handle the load if the power is to much the circuit breaker will open cutting off the power.

An overloaded circuit is when you have too much power on a line. You need extra lines to separate the load and preventing having too much power on one.

Is it possible for the velocity of an object to be zero and its acceleration not zero?

Nesterboy [21]

Explanation:

Yes, it is possible to have zero speed while accelerating, but only for a moment. ... acceleration is the rate at which the speed and direction of an object changes over time, so whenever an object goes through zero speed while reversing directions, it has non-acceleration. zero but a speed of zero.

Consider a bicycle wheel to be a ring of radius 30 cm and mass 1.5 kg. Neglect the mass of the axle and sprocket. If a force of

Charra [1.4K]

To solve the problem it is necessary to apply the Torque equations and their respective definitions.

The Torque is defined as,

$\tau = I \alpha$

Where,

I=Inertial Moment

$\alpha =$ Angular acceleration

Also Torque with linear equation is defined as,

$\tau = F*d$

Where,

F = Force

d= distance

Our dates are given as,

R = 30 cm = 0.3m

m = 1.5 kg

F = 20 N

r = 4.0 cm = 0.04 m

t = 4.0s

Therefore matching two equation we have that,

$d*F = I\alpha$

For a wheel the moment inertia is defined as,

I= mR2, replacing we have

$d*F= \frac{mR^2a}{R}$

$d*F= mRa$

$a = \frac{rF}{ mR}$

$a = \frac{0.04*20}{1.5*0.3}$

$a=1.77 m/s^2$

Then the velocity of the wheel is

$V = a *t \\V=1.77*4 \\V=7.11 m/s$

Therefore the correct answer is D.

Two satellites orbit the Earth in circular orbits of the same radius. One satellite is twice as massive as the other. Which stat

loris [4]

To solve this problem it is necessary to apply the concepts related to the orbital velocity of a satellite on earth.

This concept is expressed in the equation,

$v = \sqrt{\frac{Gm_E}{r}}$

Where,

G = Universal Gravitational constant

$m_E =$ Mass of the Earth

Therefore the ratio of the velocity from two satellites is,

$\frac{v_1}{v_2} = \sqrt{\frac{r_2}{r_1}}$

The ratio between the two satellites is the same, then

$\frac{v_1}{v_2} = \sqrt{\frac{r}{r}}$

$\frac{v_1}{v_2} = 1$

$v_1 =v_2$

Therefore the correct option is B.

Which of these accurately identify characteristics of light and mechanical waves? Select the TWO (2) that apply.

Tanzania [10]

The two correct statement are A and B. Light waves are electromagnetic waves that can travel through a vacuum. Mechanical waves can travel through a vacuum.

<h3>What is an electromagnetic wave?</h3>

EM waves are the electromagnetic radiations are made up of electromagnetic waves created when an electric field collides with a magnetic field.

Electromagnetic waves may alternatively be defined as the combination of oscillating electric and magnetic fields.

Electrically charged particles experiencing acceleration create electromagnetic waves, which can then interact with other charged particles and exert force on them.

The two correct statement is;

1. Light waves are electromagnetic waves that can travel through a vacuum.

2. Mechanical waves can travel through a vacuum.

Hence,two correct statement are A and B.
