happen to the magnets?
O A. They will be repelled because they are in each other's magnetic
field.
B. They will not move because they have only half of a magnetic
field.

Answer:

It will maintain its state of motion

Explanation:

The object would maintain its state of motion.

If the size and direction of the forces acting on an object are exactly balanced, then there is no net force acting on the object and the object is said to be in equilibrium.

Equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.

Explanation:

Let yellow ball be m1 = 0.5kg with u1 = 8 m/s and blue ball be m2 = 0.25 kg with u2 = - 4 m /s respectively.

After collision, blue ball travels 12 m/s.

Using conservation of Linear Momentum :

m1u1 + m2u2 = m1v1 + m2v2

0.5* 8 + 0.25 * - 4 = 0.5 * v1 + 0.25 * 12

v1 = 0 m/sec i.e. Yellow ball comes to rest.

Explanation:

Average power = change in energy / change in time

P = ΔE / Δt

P = (½ mv²) / t

P = (½ (0.825 kg) (0.620 m/s)²) / (0.021 s)

P = 7.55 Watts

Answer:

liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

The atoms of solids and liquids are different from each other in many ways as discussed below.

We have a solid and a liquid.

We have to describe how the atoms of a solid differ from the atoms of a liquid.

An Atom smallest unit into which matter can be divided without the release of electrically charged particles.

According to the question, the following differences exists between the atoms of solids and liquids -

Hence, it can be seen that the atoms of solids and liquids are quite different from each other.

Explanation:

1m/s=3.6km/hr

By Bernoulli's Principle :

[tex]P_x+\dfrac{\rho v_x^2}{2}+\rho gz_x=P_y+\dfrac{\rho v_y^2}{2}+\rho gz_y[/tex]

Since , pipe is horizontal so every point is at same height .

So , [tex]z_x=z_y[/tex] .

The equation will reduced to :

[tex]P_x+\dfrac{\rho v_x^2}{2}=P_y+\dfrac{\rho v_y^2}{2}[/tex]    ..... 1 )

Also flow rate will be constant :

[tex]Q=A_xv_x=A_yv_y[/tex]

[tex]v_x=\dfrac{Q}{A_x}\\\\v_x=\dfrac{2.4\times 10^{-4}}{3\times 10^{-4}}\ m/s\\\\v_x=0.8\ m/s[/tex]

[tex]v_y=\dfrac{Q}{A_y}\\\\v_y=\dfrac{2.4\times 10^{-4}}{0.6\times 10^{-4}}\ m/s\\\\v_x=4\ m/s[/tex]

Now ,

[tex]P_x-P_y=\dfrac{\rho v_y^2}{2}-\dfrac{\rho v_x^2}{2}\\\\P_x-P_y=\rho[\dfrac{ v_y^2}{2}-\dfrac{v_x^2}{2}]\\\\P_x-P_y=1000\times [\dfrac{ 4^2}{2}-\dfrac{0.8^2}{2}]\\\\P_x-P_y=7680\ Pa[/tex]

Difference in pressure between X and Y is most near to 7700 Pa.

Hence, this is the required solution.

Explanation:

particles in a solid do vibrate but they're tightly packed and move around fixed location

Answer:

see below

Explanation:

1. density = mass / volume

2. kg/mL,  g/cm³

3. volume = mass / density

4. mass = density x volume

5.  

d = m / v

d = 32.9 g / 45.78 mL

d = 0.72 g/mL

6.

vol = m / d

vol = 0.62 g / 120g/cm³

vol = 0.00517 cm³

7.

m = v * d

m = 2.07 g/mL * 60.9 mL

m = 126.063 g

5p = 8p + 18 <-- Moving constants to one side; add the same number of +14 to both sides.

-3p = 18. <-- The same thing with the variable itself.

p = -6 <-- Divide both sides by negative 3.

1225 ÷ 9 = 136.11

Which is 136 hours 11 minutes.

Answer:

collision between truck

Explanation:

Answer. Collision between trucks, because more is the mass, more is the inertia and therefore more is the momentum. Mass of the trucks is more than that of cars so collision of trucks will cause more damage.

Speed = 25.3 m/s

Time taken = 9.6 s

Calculate the distance covered by a body.

Speed = Distance/Time

We know,

Speed = Distance/Time

[tex] \bf\implies \: 25.3 = \frac{Distance}{9.6} [/tex]

[tex] \bf \implies \: Distance = 25.3 \times 9.6[/tex]

[tex] \bf\implies \: Distance = 242.88 \: m \: (approx)[/tex]

Answer:

the average speed on the bus =  1.55 m/s

Explanation:

From the information we are being provided with ;

a city block travels 6 blocks due east

and 8 blocks due north

the length of the individual blocks = 100m

As such their respective distance will be

distance (d) traveled due east direction by bus = 6 × 100 = 600 m

distance (d) traveled towards the north direction by bus = 8 × 100 = 800 m

The total distance covered  = (600+ 800)m

= 1400 m

However, it requires 15 minutes to travel this distance by bus.

Thus,  

the average speed = distance/ time

the average speed on the bus = 1400 m / (15 × 60) s

the average speed on the bus =  1400 m / 900 s

the average speed on the bus =  1.55 m/s

Multiply field strength (N/kg) by mass (kg) to get weight (N)

At the start, the car is carrying

4.7 kg * (9.8 N/kg) = 46.06 N

of fuel.

At the end, it is carrying

3.0 kg * (9.8 N/kg) = 29.4 N.

Assuming the car remains completely intact, its weight was reduced by

46.06 N - 29.4 N = 16.66 N.

Answer:

Answer:

8333

Explanation:

300km/hr = 300/60 = 5 km per min

5km/min = 5/60 = .08333333km per sec

km to cm = 100000, so

.083333 * 100000 = 8333

The train would travel at a speed of 8333.33 centimeters/second.

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second. The generally considered unit for speed is a meter per second.

As given in the problem the world record for the fastest train on Earth was set by a bullet train from Tokyo to Osaka in Japan. Without passengers, it can travel at a speed of 300 kilometers/hour,

1 kilometer = 1000 meters

1 meter = 100 centimeters

300 kilometers = 300×100000  centimeters

the speed of the fastest train = 300×100000  centimeters /3600 seconds

                                                = 8333.33 centimeters/second

Thus, the speed of the fastest train would be 8333.33 centimeters/second
