I think top. of a mountain

Answer: You would weigh very slightly more at sea level than at the top of a mountain, not enough for you to notice, but a measurable amount. Weight, which really means gravitational force, is proportional to the product of the masses of two objects acting on each other, in this case the giant earth and the minuscule you.

Answer:

240000 Joules

Explanation:

Applying,

The work that must be done by the frictional force of the brake to stop the car must be equal to the kinetic energy of the car.

W = mv²/2.................. Equation 1

Where W = work done by the frictional force of the brake, m = mass of the car, v = velocity of the car.

From the question,

Given: m = 1200 kg, v = 20 m/s

Substitute these values into equation 1

W = (1200×20²)/2

W = 240000 Joules

Answer:

f/4

Explanation:

Explanation: Gravitational force between two objects varies directly as their masses and inversely as the square of the distance between them. So, when the masses of both objects are halved without changing the distance, the gravitational force between them would become one-fourth of the original value

Answer:

They come from metal elements or alloys.

Explanation:

Different materials produce magnets of varying strengths. Ceramic magnets, also known as ferric magnets, are made of iron oxide in a ceramic composite. Samarium cobalt magnets are created from the combination of cobalt and samarium, which is a rare-earth element. Neodymium magnets contain boron, iron and neodymium, also a rare-earth element. The strongest naturally occurring magnet is lodestone, a form of magnetite. It attracts even small objects, such as staples and paper clips.

Answer:

C a fast-moving cold front moved through the area.

Explanation:

This is because, since there is a there is a thunderstorm and high winds in the area, this can only be caused by a fast moving front. Also there is a temperature drop, this can only be caused by the fast moving cold front since a cold front has a low temperature.

Thus, for the area to experience thunderstorms with high winds and a drop in temperature, a fast-moving cold front moved through the area.

Bang on a drum.  

Explanation:

Amplitude is making loud sounds

Answer:

a) v'=0 ,  B)  v'= 125 miles/h

Explanation:

This is a relative speed exercise, the speed of a body is

          v ’= v - u

where v is the speed with respect to the Earth and u the speed of the reference frame with respect to which we want to calculate

a) with respect to a car traveling east at u = 60 miles / h

          v ’= 60 -60

          v ’= 0

with respect to this vehicle the speed of the car is zero

b) with respect to a truck traveling west at u = -65 miles / h

           v = 60 - (-65)

           v = 125 miles / h

Answer:

Speed-time graph C

Explanation:

The speed of the ball is constant towards surface of Moon since no forces acting.

Speed of ball increases as ball approaches the surface of Earth.

A body's surface gravity is directly proportional to its mass, but inversely related to the square of its radius. Thus, option C is correct.

The mass of the Earth's moon is significantly lower than that of the planet. The Moon is not just smaller than Earth, but it is also only around 60% as dense. On the Moon, there is less gravitational field attraction than on Earth, hence a person weighs less there.

The Moon's surface gravity is about 1/6th as powerful as Earth's, or 1.6 meters per second every second. The Moon's surface gravity is lower because it has a smaller mass than Earth.

Due to the absence of forces, the ball is moving toward the surface of the moon at a constant speed.

Therefore, The speed of the ball rises as it gets closer to the Earth's surface.

Answer:

1. La velocidad del vehículo en su trayectoria de descenso es 65.2 m/s.

2. El vehículo forma un ángulo de 57.5° con la vertical.

Explanation:

1. La magnitud de la velocidad del vehículo está dada por la suma de las componentes del vector en la dirección vertical (y) y horizontal (x):

[tex] v^{2} = v_{x}^{2} + v_{y}^{2} [/tex]

[tex] v = \sqrt{v_{x}^{2} + v_{y}^{2}} = \sqrt{(55 m/s)^{2} + (35 m/s)^{2}} = 65.2 m/s [/tex]

Entonces, la velocidad del vehículo en su trayectoria de descenso es 65.2 m/s.

2. El ángulo que forma la trayectoria con la vertical se puede calcular con trigonometría:

[tex] tan(\theta) = \frac{v_{x}}{v_{y}} [/tex]

[tex] \theta = tan^{-1}(\frac{v_{x}}{v_{y}}) = tan^{-1}(\frac{55}{35}) = 57.5 ^{\circ} [/tex]

Por lo tanto, el vehículo forma un ángulo de 57.5° con la vertical.

Answer:

Increasing temperatures evaporate water faster, causing an increase in salinity.

Explanation:

When the water molecules of the ocean become heated, they expand. ... Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity.

The correct option is C, increasing temperatures cause faster evaporation of water which results in an increase in salinity.

Hence we can conclude that as the temperature rises, the process of evaporation takes place more rapidly which decrease the concentration of salt in water, which leads to higher salinity.

We need to find the time it take the light to travel that distance. Let the time be t. We know that,

speed = distance/time

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{1609}{3\cdot10^{8}}\\\\=5.36\times 10^{-6}\ s[/tex]

E: None of the above

Explanation:

Since the force on the wire F = ∫idL × B where i = current in wire = 2.0 mA = 2.0 × 10⁻³ A, dL = vector length of wire = dyj and we integrate from y₁ = 0 m and y₂ = 0.25 m, and B = magnetic field = (0.3y)i + (0.4y)j

So, F = ∫idL × B

and we integrate from y₁ = 0 m and y₂ = 0.25 m

F = 2.0 × 10⁻³ A∫₀⁰°²⁵[dyj m × (0.3y)i + (0.4y)j]

F = 2.0 × 10⁻³ A∫₀⁰°²⁵[dyj m × (0.3y)i + dyj m × (0.4y)j]

F = 2.0 × 10⁻³ A∫₀⁰°²⁵[(0.3y) × dy(j × i) + 0.25 × (0.4y)(j × j)]

F = 2.0 × 10⁻³ A∫₀⁰°²°⁵[(0.3ydy(-k) + 0.1y)(0)]

F = 2.0 × 10⁻³ A∫₀⁰°²⁵(-0.3ydy)k

F = 2.0 × 10⁻³ A[-0.3y²/2]₀⁰°²⁵k

F = -2.0 × 10⁻³ A[0.3(0.25)²/2 - 0.3(0)²/2]k

F = -2.0 × 10⁻³ A[0.3(0.0625)/2 - 0]k

F = -2.0 × 10⁻³ A[0.3(0.0625)/2]k

F = -1 × 10⁻³[0.01875]k N

F = -[0.01875 × 10⁻³]k N

F = -[1.875 × 10⁻⁵]k N

Answer:

c. Closing the valve stops the flow of water, but opening a switch stops the flow of charges.

Explanation:

I just took the test on edge. Hope this helps and sorry if I'm late :)

Closing the valve stops the flow of water, but opening a switch stops the flow of charges.

Simple circuit: It consists of a switch, a bulb, and a cell. These parts are linked together by metal connecting wires to form a circuit.

Closing the switch turns on the lamp. This is because the electric current can circulate along a continuous path of metal. The current could not flow if the circuit had any breaks.

The circuit is completely filled with current. The cell moves the circuit's current with its assistance. The lamp is lit up as the current flows through it.

Therefore, Closing the valve stops the flow of water, but opening a switch stops the flow of charges.
