Two permanent magnets produce a magnetic field pattern as shown below.

Answer:

The skater has mechanical/gravitational potential energy at the two meter mark. The skater gets to two meters high on the other end of the ramp. In terms of the conservation of energy, the skater will never go higher than two meter on the other end of the the ramp because energy can be neither created nor destroyed.

Explanation:

I hoping it is right!!!∪∧∪     ∪ω∪

Answer:

the reason it wont go higher is because some of the energy converts into thermal energy

Answer:

the labor rate variance is $416 favorable

Explanation:

The computation of the labor rate variance is shown below:

But before that actual labor rate is

The Actual labor rate is

= Actual direct labor cost ÷ Actual labor hours

= $103,840 ÷ 2,896

= $35.856354

Now  

labor rate variance is

= (Standard rate - Actual rate) × Actual Hours

= ($36 - $35.856354) × 2,896

= $416 Favorable

Hence, the labor rate variance is $416 favorable

Answer: The answer is resistors

Explanation: I just took the unit test and it was correct

Answer:

Explanation:

According to newton's second law:

Force = mass * acceleration

Given

Mass = 873kg

acceleration = 44.66m/s²

Magnitude of the force is expressed as;

F = ma

F = 873 * 44.6

F = 38,673.9N

Hence the magnitude of the net force exerted on the dragster during this time is 38,673.9N

Answer:

6.77 x 10^-13 Newtons

Explanation:

using the formula [tex]F= \frac{GMm}{r^2}[/tex]

where G is the gravitation constant which is 6.673 x 10^-11 N m2/kg2

M = mass of the first object which is 0.25 kg

m = mass of the second object which is 0.65 kg

and r is the distance between the objects which is 4 metres

Plugging our values in:

[tex]F\:=\:\left(6.673x10^{-11}\right)\frac{\left(0.25\right)\left(0.65\right)}{4^2}[/tex]

F = 6.77 x 10^-13 N

Answer:

Answer is: 162 g of beryllium.

Chemical reaction: Be + 2H₂O → Be(OH)₂ + H₂.

m(H₂) = 36,0 g.

m(Be) = ?

n(H₂) = m(H₂) ÷ M(H₂)

n(H₂) = 36,0 g ÷ 2 g/mol = 18 mol.

from reaction: n(Be) : n(H₂) = 1 : 1.

n(Be) = n(H₂) = 18 mol.

m(Be) = n(Be) · M(Be).

n(Be) = 18 mol · 9 g/mol = 162 g.

Answer:

Answer is: 162 g of beryllium.

Chemical reaction: Be + 2H₂O → Be(OH)₂ + H₂.

m(H₂) = 36,0 g.

m(Be) = ?

n(H₂) = m(H₂) ÷ M(H₂)

n(H₂) = 36,0 g ÷ 2 g/mol = 18 mol.

from reaction: n(Be) : n(H₂) = 1 : 1.

n(Be) = n(H₂) = 18 mol.

m(Be) = n(Be) · M(Be).

n(Be) = 18 mol · 9 g/mol = 162 g.

To find the radius formed by melting the wire, you must start with this equation:

volume of wire = volume of sphere (since it is simply melted into a different shape, the volume would remain the same, equal)

πr²l = 4/3πr³

cancel π:

r²l = 4/3r³

3r²l = 4r³

r³ = (3r²l)/4

r³ = (3 × 3² × 200)/4

r³ = 1350

r = (cube root) of 1350

r = 11.052094....

r = 11.05 mm

divide by 1000 to get the answer in the unit meters:

r = 0.01105m

Answer:

d = - 10 [m]

Explanation:

We must remember that speed is defined as the relationship between the displacement in a given time. In this way, we can propose the following equation.

[tex]v = d/t[/tex]

where:

v = velocity = 2 [m/s]

d = displacement [m]

t = time = 5 [s]

Now replacing:

Answer:

a) N = 343 [N]

Explanation:

We must remember Newton's third law, which tells us that the force acting on a body is equal to the normal reaction force of equal magnitude but acting in the opposite direction.

[tex]N=m*g[/tex]

where:

m = mass = 35 [kg]

g = gravity acceleration = 9.81 [m/s²]

[tex]N = 35*9.8\\N= 343 [N][/tex]

Answer:

Explanation:

The average velocity of the car can be found by using the formula

[tex]a = \frac{d}{t } \\ [/tex]

d is the distance

t is the time taken

From the question we have

[tex]a = \frac{200}{3} \\ = 66.66666...[/tex]

We have the final answer as

Answer:

The instantaneous velocity of the object is 250 m/s

Explanation:

Given;

time of the object motion, t = 25 s

acceleration due to gravity, g = 10 m/s²

The instantaneous velocity of the object is given as;

v = u + gt

where;

u is the initial velocity of the object = 0 (since it was released from rest)

Substitute the givens;

v = 0 + (10 x 25)

v = 250 m/s

Therefore, the instantaneous velocity of the object is 250 m/s

Answer:

333 m

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 0 m/s.

Time (t) = 8.14 s.

Final velocity (v) = 80.79 m/s.

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

Height (h) =?

v² = u² + 2gh

80.79² = 0 + (2 × 9.8 × h)

6527.0241 = 0 + 19.6h

6527.0241 = 19.6h

Divide both side by 19.6

h = 6527.0241 / 19.6

h = 333 m

Thus, the plane was at a height of 333 m when the package was dropped.

Answer: The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

Answer:

Radiant and thermal

Explanation:

Electrical and thermal don't make sense because you are not using electricity to light the match. Radiant and nuclear is not right because you are not using nuclear energy to light the match. Nuclear and kinetic isn't right because you are using kinetic and you are not using nuclear energy.
