How does the “Sum of Forces” help you?
pls helppppppppppppppp

True I guess

because if the force is balanced and there is no net force, the object will not accelerate and the velocity will remain constant...

Not sure

Answer:

The angle the new vector makes with the x-axis is 33°

Explanation:

By multiplying a vector with a scalar, we multiply the similar components of the two quantities which is the magnitude of the scalar quantity and the magnitude of the vector with the new vector formed will have a magnitude equal to the product of the two magnitudes and the same direction of the original vector as follows;

The magnitude of the vector B = 5.6

The magnitude of the scalar = 92

The product of the two magnitudes = 5.6 × 92 = 515.2

The magnitude of the new vector = 515.2

The direction of the new vector = 33° South of West

Therefore, the angle the new vector makes with the x-axis = 33°.

A material that produces magnetic field are called magnets. Magnetic poles refers to the ends of a magnet where the forces are strongest.

Magnetic poles are the regions at each end of a magnet where the external magnetic field is strongest.

A bar magnet suspended in the Earth's magnetic field orients itself north-south. A north magnetic pole is the north-seeking pole of such a magnet or any similar pole.

Thus, the correct option is D.

The length is   [tex]D  =3 \  m  [/tex]

Explanation:

The  velocity of the bullet is mathematically evaluated as

      [tex]v  =  a * t [/tex]

=>   [tex]v  = 1.5 * 2 [/tex]

=>    [tex]v  = 3 \  m/s  [/tex]    

Now from kinematic equation

       [tex]v^2  =  u^2 + 2* a  *  D[/tex]

Here  D is the length of the barrel  and  u =  0 m/s

So

     [tex]3^2  =  0 + 2* 1.5  *  D[/tex]

Answer:

The darts hit very different areas of the board.

Explanation:

The bullseye is the point at which darts are most accurate. There is no accuracy nor precision if the darts are neither close to the target nor to one another.

The degree of similarity between several measurements is known as precision.

Even if the measurements are not exactly the right value, they are very reproducible.

Throwing darts at a dartboard can be used to demonstrate accuracy and precision.

There is precision but not accuracy if every dart lands distant from the bulls-eye but extremely closely spaced apart.

In contrast to a dart that lands far from the bulls-eye, which shows poor accuracy, a dart that hits the bulls-eye is very accurate.

Therefore, The board was struck by the darts in a variety of ways.

Answer:

Venus has phases similar to the moon’s phases.

Explanation:

i hope this helped you :)

Answer:

Compasses are mainly used in navigation to find direction on the earth. This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south. Also, In a magnet all the domains are oriented in the same direction. In the case of a nail, the domains can be aligned in the same direction causing the nail to become magnetic. That is because if you hang a bar magnet from a thread, the north pole will point to magnetic north. When you bring one north pole close to another north pole they repel each other. You can feel the two magnets pushing each other apart.

Answer: Answer is D

Answer:

The value in m/s [tex]v_{a} = 111 \ m/s [/tex]

The value in km/h [tex]v_{a} = 400\ km/h [/tex]

Explanation:

Generally the average velocity of the helicopter is mathematically represented as

[tex]v_{a} = \frac{\Delta D}{ t}[/tex]

substituting [tex]3.33 km = 33.3*10^3\ for\  \Delta D[/tex] and  30.0 s for  t

We have

         [tex]v_{a} =  \frac{33.3 *10^{3}}{ 30}[/tex]

=>     [tex]v_{a} =  111 \  m/s [/tex]

Now converting to km/h

      [tex]v_{a} =  111  *  \frac{3600  *\frac{s}{h} }{1*10^{-3} *\frac{km}{m}} [/tex]

=>  [tex]v_{a} = 400\  km/h [/tex]

Answer:

the ant

Explanation:

because work is done when there will be involvement of displacement in the direction of the force.

Answer:

The ant is doing work but the elephant is not

Explanation:

Work done = Force × Displacement

In case of ant and housefly,

Ants are dragging the housefly , so they are displacing the housefly from one point to the other by applying certain force , so we can say that they are doing work

In case of elephant and tree,

When the elephant is pushing the tree( applying force) , the tree is not moving which means that there is no Displacement, so work done will be

Work done = Force × Displacement

= Force × 0

= 0

First find the diameter of each.

Jupiter’s diameter is 86,881 mi.

Earth’s diameter is 7,917.5 mi.

Then divide those two.

Rounded, Jupiter is 11 times larger.

unrounded: 10.9732870224186927691821913482791285127

Finding out how large something is compared to something can be done by dividing.

For example I have two dogs. One dog is 3 feet tall. The other is 2 feet tall. How much taller is dog one? Dog one is 1.5 times larger because 3/2 = 1.5 AND 2 x 1.5 = 3.

So for this case multiplying Earth’s diameter by 10.9732870224186927691821913482791285127 will give you Jupiter’s diameter.

Answer:

its B

Explanation:

Answer:

Voltage is a measure of how much energy is delivered to charge. At its most basic, an electron (basic charge) is imparted 1.602×10^−19 joules when moved through an electric potential difference of one volt. An electron is then said to have an energy of 1 electronvolt. So, voltage is energy divided by charge.
