The answer is 118 J :)

Explanation:

38 +80 = 118.

Answer:

The correct answer is 1.3Hz

Answer:

15 m/s

Explanation:

0.3 + 0.2 = 0.5

0.5 * 10 = 5

5 + 10 = 15

Answer:

if somthing is warm or if somthing moves it usally has energy

The basketball's angular velocity ω at time t is

ω = 27 rad/s + (-0.15 rad/s²) t

It comes to a stop when ω = 0, which happens for

0 = 27 rad/s - (0.15 rad/s²) t

t = (27 rad/s) / (0.15 rad/s²)

t = 180 s

In this time, the ball would undergoes an angular displacement θ of

θ = (27 rad/s) t + 1/2 (-0.15 rad/s²) t ²

Plug in t = 180 s and solve for θ :

θ = (27 rad/s) (180 s) - 1/2 (0.15 rad/s²) (180 s)² = 2430 rad

One complete revolution corresponds to a turn of 2π rad, so the ball makes

(2430 rad) / (2π rad/rev) ≈ 386.747 rev

or about 387 revolutions as it slows down.

Answer:

0.78 m

Explanation:

us the formula

speed = frequency x wavelength

343 = 440 x wavelength

343 / 440 = wavelength

wavelength = 0.78 m

I think the last option, you wrote wrongly, it is supposed to be 0.78 not 0.078 .

if you think I am wrong please do tell me, I will redo this.

hope this helps

Answer:

2km/min

Explanation:

Velocity= change in distance / time taken

Velocity = 20km/10min=2km/min south

South is placed there to show what direction she went, as velocity has both magnitude and direction

Answer:

55.56%

Explanation:

We'll begin by calculating the work done in pushing the wedge. This can be obtained as follow:

Force (F) = 900 N

Distance (s) = 0.1 m

Workdone (Wd) =..?

Wd = F × s

Wd = 900 × 0.1

Wd = 90 J

Finally, we shall determine the efficiency. This can be obtained as follow:

Work output = 50 J

Work input = 90 J

Efficiency =?

Efficiency = work output / work input

Efficiency = 50 / 90 × 100

Efficiency = 55.56%

Thus, the efficiency is 55.56%

Answer:

Fossil fuels take millions of years to replenish

Answer:

Fossil Fuel is limited it is like coal there is a limit and it won't last forever. This also contributes that it is not safe for the environment as well as the safety and health of people. This is similar to when there are many factories around an area there is going to be a high percentage of respiratory diseases such as asthma.

Explanation:

Rusting is a chemical reaction because it is the process of oxidation of a metal.  

Answer:

Explanation:

Answer:

i think it would be a but i am not 100% sure on that

Answer:

700 Joules

Explanation:

The work done equals force times distance. Just multiply your two values there.

Side note: It would be more impressive if he'd done it in 1 second rather than 5. You know why? Because POWER=WORK/TIME. The less time it takes him to lift the weight with the same force and distance, the more powerful he is!

Answer:

C. Neap Tides

Explanation:

Answer:

c neap tides

Explanation:

The spring constant of the given bow spring is equal to  1.77 × 10⁵ N/m.

Hooke's law can be described as a law that states that the force (F) required to extend or compress a spring by displacement linearly with respect to that displacement along a straight line.

The spring force can be represented in the form of an equation:

F = -kx

where k is a spring constant of the spring and x is the deformation of the spring. The negative sign shows that force is restoring force.

The energy that can be stored in the spring when it is stretched is given by:

E = (1/2)kx²

Given, the energy stored in the spring when it is stretched, E = 1000J

The distance by which the bow spring is stretched, x = 0.15 m

2000 =  (1/2) × k (0.15)²

k = 1.77 × 10⁵ N/m

Answer:

Answer:

If the track is horizontal and the string is pulled horizontally, the friction on the cart would be [tex]4.0\; \rm N[/tex].

Explanation:

Let [tex]m[/tex] denote the mass of this cart, and let [tex]a[/tex] denote the acceleration of this cart.

[tex]m = 3.00\; \rm kg[/tex].

[tex]a = 2.00\; \rm m \cdot s^{-2}[/tex].

Apply Newton's Second Law to find the net force on this cart.

[tex]\begin{aligned}\text{Net Force} &= m \cdot a\\ &= 3.00\; \rm kg \times 2.00\; \rm m\cdot s^{-2}\\ &= 6.00\; \rm N\end{aligned}[/tex].

The following forces act upon this cart:

Assume that the track is horizontal, and that the string was pulled horizontally. The normal force from the track would exactly balance the downward gravitational attraction from the earth. Hence, the [tex]6.00\; \rm N[/tex] net force on this cart would be equal (in size) to the size of the tension from the string ([tex]10.0\; \rm N[/tex]) minus the size of the friction from the track.

In other words:

[tex]\begin{aligned}&\text{Size of Net Force}\\ &= \text{Size of Tension} - \text{size of friction}\end{aligned}[/tex].

[tex]\begin{aligned}& 6.00\;\rm N = 10.0\; \rm N - (\text{size of friction})\end{aligned}[/tex].

[tex]\text{size of friction} = 10.0\; \rm N - 6.00\; \rm N = 4.0\; \rm N[/tex].

Answer:

When an object slows down, its acceleration is opposite to the direction of its motion. This is known as deceleration.

Answer:An electromagnet is a magnet that works with electricity. It can be switched on and off. The coils are nearly always made of copper wire because copper is such an excellent electrical conductor. Electromagnets have many uses.Permanent magnets are mainly used in small generators, and they have the advantage that they don't need a power supply. Electric magnets are iron or steel wound with wire. When electricity passes through the wire, the metal becomes magnetic and creates a magnetic field.
