a resistance of 60ohms allows 0.4 amps of current to flow when it is connected across a battery. what is the voltage of the battery?

Answers

Answer 1

Answer:

V = 24 [V]

Explanation:

To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of resistance by the current.

V = I*R

where:

V = voltage [V]

I = current [amp]

R = resistance [ohm]

Therefore:

V = 0.4*60

V = 24 [V]

The potential energy that depends on height is called gravitational potential energy. (Option B)

What is gravitational potential energy?

Gravitational potential energy is a form of potential energy that an object possesses due to its position relative to a gravitational field.

When an object is raised to a certain height above the ground, it gains gravitational potential energy. The higher the object is raised, the greater its potential energy.

This potential energy is a measure of the work that would be required to move the object against gravity and bring it back down to its original position.

The formula for gravitational potential energy is;

Potential Energy (PE) = mg h

where;

PE is the gravitational potential energym is the mass of the objectg is the acceleration due to gravityh is the height or elevation of the object

Ben has two carts with masses of 0.1 kg and 0.2 kg. He pushes the smaller cart toward the larger cart and they collide. The smaller cart rebounds back in the direction it came from. He measures the force on the smaller cart from the larger cart to be 5 N. What was the magnitude of the acceleration of the smaller cart?

Answers

Answer:

The acceleration of the smaller cart is 50 m/s²

Explanation:

The given masses of the carts are 0.1 kg and 0.2 kg

The direction in which the small cart bounces = In the revers to its initial direction

The force exerted by the larger cart on the small cart = 5 N

Therefore, we have;

Force acting on smaller cart = Mass of smaller cart  × Acceleration of the smaller cart

∴ The acceleration of the smaller cart = Force acting on smaller cart/(Mass of smaller cart)

The acceleration of the smaller cart = 5 N/(0.1 kg) = 50 m/s²

The acceleration of the smaller cart = 50 m/s².

how much force is needed to accelerate 300 kg at a rate of 4 m/s/s​

Answers

Answer:

1200

Explanation:

Force = Mass x Acceleration

Answer:

[tex]\boxed {\tt 1,200 \ Newtons }[/tex]

Explanation:

Force can be found by multiplying the mass by the acceleration.

[tex]F=m*a[/tex]

The mass is 300 kilograms.

The acceleration is 4 meters per second squared.

[tex]m= 300 \ kg\\a= 4 \ m/s^2[/tex]

Substitute the values into the formula.

[tex]F= 300 \ kg * 4 \ m/s^2[/tex]

Multiply.

[tex]F= 1200 \ kg * m/s^2[/tex]

1 Newton is equal to 1 kilograms meters per second squared, so our current answer of 1200 kg m/s² is equal to 1200 Newtons.

[tex]F= 1200 \ N[/tex]

The force needed is 1,200 Newtons.

23. A ball is dropped from 215m. How long will it take to reach the ground?

Answers

Answer:

6.6 s.

Explanation:

From the question given above, the following data were obtained:

Height (h) = 215 m

Time (t) =..?

Thus, we can obtain the time taken for the ball to get to the ground by applying the following formula:

h = ½gt²

Where:

h is the height.

g is the acceleration due to gravity

t is the time to taken.

With the above formula, the time taken for the ball to get to the ground can be obtained as follow:

Height (h) = 215 m

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) =..?

h = ½gt²

215 = ½ × 9.8 × t²

215 = 4.9 × t²

Divide both side by 4.9

215 / 4.9 = t²

Take the square root of both side.

t = √(215 / 4.9)

t = 6.6 s

Therefore, it will take 6.6 s for the ball to get to the ground.

Answers

Answer:

1) [tex]V_{1}[/tex]= 100ml = 0.1 L

2) [tex]P_{1}[/tex]= 50kPa

[tex]1) P_{2} =400 kPa\\2)V_{2} =?[/tex]

So,

    [tex]P_{1}V_{1} = P_{2} V_{2}[/tex]

     [tex]V_{2} = \frac{0.1 x 50}{400}[/tex]

     [tex]V_{2} = 0.0125 L[/tex]

[tex]P_{1} V_{1} =P_{2} V_{2}\\ P_{2}=\frac{0.1x103}{2}\\ P_{2}=5.15 kPa[/tex]

[tex]4) V_{1}=2 cm^{3} = 0.002 dm^3\\P_{1} =3 atm x 760 = 2280 torr\\P_{2} = 0.0200 atm x 760=15.2 torr[/tex]

Same, formula as above,

Answers

B is the answer because a solid would not be able to hold its shape if it was able to move around

Answer:

B. The particles in solids have a fixed position but can vibrate

Explanation:

Answer choice "A" is incorrect because particles in gases are not held by bonds and move freely (not fixed).

Answer choice "C" is incorrect because while solids are close in proximity, their particles do not move past each other.

Answer choice "D" is incorrect because while the particles in gases are able to move past each other, they are not arranged in close proximity. In fact, them being spread out and free is why they are able to move past each other.
