I have the answer, but I don’t know how to get the answer. Can anyone explain how to get it?

Answerpov:

Explanation:

In order to increase the momentum of the ball, you have to increase its speed.

The first and third choices on the list ('A' and 'C') will do that.

The factors that will increase momentum of a rolling ball are:

A. Moving from a flat surface to moving downhill.

C. A moving object traveling in the same direction as the ball colliding with it.

The gravitational power of the Earth ready makes the ball speed up, and in this manner pick up speed.

If you increase either mass or velocity, the momentum of the object increases proportionally.

Thus, the factors that increase the momentum of a rolling ball are

A. Moving from a flat surface to moving downhill.

C. A moving object traveling in the same direction as the ball colliding with it.

Answer:

Temperature decreases as depth increases (generally)

Explanation:

In general, sunlight will heat the upper level of water.  As you go deeper into the water, the sunlight cannot reach as easily so the temperature is lower.

There are exceptions considering underwater currents like the Gulf Stream or volcanic vents.

→ Uses of Convex Mirror

• Convex mirrors are often used in the hallways of buildings including stores, schools, hospitals, hotels and apartment buildings.

• They are used in driveways, roads, and alleys to provide safety to all the bikers and motorists at curves and turns and other places where there is a lack of visibility.

• They are also used in some automated teller machines as a handy security feature that allow user to see what all is happening behind them.

• They are used in passenger side mirror on a car and somewhere it is labelled as “objects in mirror are closer than they appear” to warn the driver.

→ Uses of concave mirror :

• Head mirrors

• Shaving mirrors

• Headlights

• Ophthalmoscope (optical instrument)

• Solar furnaces

• Astronomical telescopes

Answer:

the pressure within the atmosphere of Earth

Explanation:

Atmospheric pressure is a force in an area pushed against a surface by the weight of the atmosphere of the earth.

→ The charge in electron charge Q(e) is equal to the charge in coulombs Q(C) times 6.24150975⋅1018:

1C = 6.24150975⋅10¹⁸e

Q(e) = Q(C) × 6.24150975 × 10¹⁸

Q(e) = 96,500 × 6.24150975 × 10¹⁸

Q(e) = 6.02305690875 × 10²³

which is round off to

→ 6.03 × 10²³ electrons

Answer:

Explanation:

W = 25 Watts

V = 12.6 Volts

I = ? I is the current in amperes.

Solution

25 = 12.6 * I

I = 25 / 12.6

I = 1.98 amperes

V = 12.6

I = 1.98

R = ??

V = I * R

12.6 = 1.98 * R

R = 12.6 / 1.98

R = 6.35 ohms

Answer:

The force by which a substance (magnet) attracts a body(metals) towards it is called magnetic force

Answer:

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

The second ball traveled a greater distance when compared to the first ball because the second ball spent more time in motion.

The given parameters;

The distance traveled by each ball is calculated using the second equation of motion as shown below.

The distance traveled by the first ball is calculated as follows;

[tex]h = u_0t + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 1^2)\\\\h = 4.9 \ m[/tex]

The distance traveled by the second ball is calculated as follows;

[tex]h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 3^2)\\\\h = 44.1\ m[/tex]

Thus, the second ball traveled a greater distance because it spent more time in motion.

La adicion de vectores permite encontrar la repuesta para la velocidad resultante del avión es:

Las magnitudes vectoriales son cantidades tienen modulo y dirección, la velocidad es una de estas magnitudes, por lo tanto deben ser sumada usando álgebra vectorial.

Un sistema de referencia es un sistema desde donde realizar las mediciones, en este caso indican que usemos un sistema de los puntos cardinales.

En el adjunto podemos ver un esquema de los vectores velocidad y su resultante, realicemos el calculo de la resultante por método analíticos

Indican que el valor de la velocidad hacia el Este es vₓ = 20 m/s y la velocidad hacia el Norte es v_y = 90 m/s, por lo tanto, para la magnitud usamos el Teorema de Pitágoras

           [tex]R= \sqrt{v_x^2 + v_y^2}[/tex]

           R = [tex]\sqrt{20^2 + 90^2}[/tex]

          R = 92,2 m/s

Para encontrar la direccion usemos trigonometría

          tan θ = [tex]\frac{v_y}{v_x}[/tex]

          θ = tan⁻¹ [tex]\frac{v_y}{v_x}[/tex]

          θ = tan⁻¹ 20/90

          θ = 12,5º

La dirección se lee 12,5º al Norte del Este

Answer:

answer 7m/s^2

Explanation:

›»› The Acceleration of jumper = 7 m/s²

Given :

Initial velocity of jumper (u) = 0 m/s

Final velocity of jumper (v) = 10.5 m/s

Time taken by jumper (t) = 1.5 sec

To Find :

Acceleration of jumper (a) = ?

Required Solution :

→ Initial velocity (u) = 0 m/s (because jumper increase from zero)

† From first equation of motion

⇒ v = u + at

⇒ 10.5 = 0 + a × 1.5

⇒ 10.5 = 0 + 1.5a

⇒ 10.5 = 1.5a

⇒ a = 10.5/1.5

⇒ a = 7 m/s²

║Hence, the Acceleration of jumper is 7 m/s².║

Additional Information :

★ First equation of motion :

⪼ v = u + at

Where,

v is the Final velocity in m/s.

u is the Initial velocity in m/s.

Where,

s is the Distance travelled in m.

u is the Initial velocity in m/s.

a is the Acceleration in m/s².

★ Third equation of motion :

⪼ v² = u² + 2as

Where,

u is the Initial velocity in m/s.

a is the Acceleration in m/s².

s is the Distance travelled in m.

Answer:

Answer: Pressure is directly proportional to force and inversely proportional to area.

Explanation: Pressure is defined as the ratio of force applied to the area of cross section.

Mathematically,

P=\frac{F}{A}P=

A

F

where,

P = Pressure

F = Force applied

A = Area of cross-section

from above it is visible that pressure is directly proportional to the force applied which means that if force increases, pressure increases. It is also inversely proportional to the area of cross-section. So, when area of cross-section increases, pressure decreases.

The units of pressure are N/m^2N/m

2

and S.I. units for this term is Pascal (P).
