Answer:

50 m/s²

Explanation:

Givens:

F = 25N horizontally

m = 0.5 kg

a = ?

We are solving for a, so plug in the known values into the formula F = ma

25N = 0.5kg*a

Divide both sides by 0.5kg

(Note that 1N = 1kg*m/s², so when you divide, kg cancels out leaving you with m/s²)

50 m/s² = a

Answer:

800 N

Explanation:

The formula to solve this equation is stress = Force/ Area.

The first step is to rearrange this equation for force: Force = stress * area

The second step is to determine the area: A = pi/4 * d^2

A = pi/4 * (0.0016m)^2=0.00000201 m^2

The third step is to substitute the area back into the equation:

Force = (4 * 10^8)(0.00000201) = 804 N

804 N is approximately 800 N

Explanation:

Iliotibial band syndrome occurs when a tendon called the iliotibial band rubs against the hip or knee bones, causing it to become inflamed or swollen. The tendon runs from the top of your pelvic bone down to your knee on the outside of your leg. When it becomes overly tense, it grinds on your bones (tight).

The repetitive bending of the knee during physical activities such as running, cycling, swimming, and hiking is a common cause of iliotibial (IT) band syndrome. Fascia, or connective tissue, makes up the IT band. It is an elastic collection of fibers that extends from the hip to below the knee along the thigh.

If the force which act on object increased to triple it's value and the area decreased nine times the the pressure will..?

The pressure will decrease 3 times.

Answer:

Effort=300N

Load=900N

Load distance=20m

Now,

Ed=(L*Ld)/E

Ed=(900*20)/300

Ed=1800/300

Ed=6m

Explanation:

Answer:

This is the correct answer!

Effort=300N

Load=900N

Load distance=20m

Now,

Ed=(L*Ld)/E

Ed=(900*20)/300

Ed=1800/300

Ed=6m

Hence, the distance from fulcrum to effort is 6 m

Answer:

An electromagnet is a magnet that magnetic field is generated by an electric current. Wire coiled into a coil is used to make electromagnets. A current flowing through the wire produces a magnetic field that is focused in the hole, which serves as the coil's core.

Solution :-

As per the provided information in the given question, we have been given that the Power of the Device is 400 Watt . Voltage is given 220 Volt . And, we have been asked to calculate the Current of the Device .

For calculating the Current , we will use the Formula :-

Therefore , by Substituting the given values in the above Formula :-

⇒ Current = Power / Voltage

⇒ Current = 400 / 220

⇒ Current = 1.81

Hence :-

Answer:

I think the answer is B

Explanation:

If the Voltage is halved, then the current goes down as well so the voltage drop across the lamps will decrease as well.

Answer:

2 π Θ = 360      where Θ is the angle of 1 rad = 57.3 deg

W = R Θ = 2200 m * 10 / 57.3 = 384 m

Note: The difference between radian measure (distance along arc of circle) and the chord of a circle is quite small for 10 deg - probably the cloud is not completely flat anyway

Please mark me as brainliest

Answer:

Conduction is usually faster in certain solids and liquids than in gases. Materials that are good conductors of thermal energy are called thermal conductors. Metals are especially good thermal conductors because they have freely moving electrons that can transfer thermal energy quickly and easily.

Heat transfer by convection happens through the air, and there are millions of minuscule air spaces between the fibers. Heat transfer by radiation is also slow since one fiber must radiate its heat to another.

When we give heat then kinetic energy is increase and this heat is transferred from hot metal to cold metal through this free electrons. As in insulator the free electrons are negligible so that the heat is not transferred from hot junction to cold junction due to absence of this free electrons.

D.) The gravitational pull of the Moon on Earth's oceans.

Explanation:

A.) is incorrect because waves caused by the moon's gravitational pull. Waves and tides are essentially the same thing.

B.) is incorrect because climate change only has a small, indirect effect on the tides (i.e., rising sea levels).

C.) is incorrect because while the gravitational pull of the Sun affects the tides to some extent, it is nowhere near as influential as the Moon's gravitational pull.

D.) is correct because the gravitational forces between the Moon and the Earth are the primary cause of the tides.

The acceleration of the ball is 0.25 m/s². Therefore option B is correct.

To determine the acceleration of the ball, we can use the equation of motion for objects moving in a straight line with constant acceleration:

[tex]\[ d = ut + \frac{1}{2}at^2 \][/tex]

where d is the distance traveled, u is the initial velocity (which is zero in this case since the ball is released from rest), a is the acceleration, and t is the time.

In this scenario, the distance traveled is 0.5 m, the initial velocity is 0 m/s, and the time taken is 2.0 s. Plugging these values into the equation, we have:

[tex]\[ 0.5 = 0 + \frac{1}{2} \cdot a \cdot (2.0)^2 \][/tex]

Simplifying the equation, we get:

[tex]\[ 0.5 = 2a \][/tex]

Dividing both sides by 2, we find:

[tex]\[ a = 0.25 \, \text{m/s}^2 \][/tex]

Therefore, the acceleration of the ball is 0.25 m/s². The correct answer is B) 0.25 m/s².

Hi there!

We can use the work-energy theorem to solve.

Recall that:
[tex]E_i = E_f[/tex]

The initial energy equals the final energy (Conservation of Energy). However, we must take into account energy dissipated due to friction in this instance.

The energy lost due to friction is equivalent to the work done by friction. Recall the following:

The work due to a force is:
[tex]W = F \cdot d \\[/tex]

Since the displacement is in the same direction as the force, the dot-product becomes Fd.

The work due to friction then becomes:

[tex]W_f = \mu mgdcos\theta[/tex]
The work due to friction is SUBTRACTED from the initial potential energy.

Initial energy = GPE = mgh

Final energy = KE

Therefore:

[tex]\boxed{mgh - \mu mgdcos\theta = KE}[/tex]
