a wagon has a mass of 12 kg it has an acceleration of 3 m/s/s 2 what is the net force that was required for the wagon to have this acceleration
Pls pls pls help me solve this problem
Answer:
[tex]\boxed {\boxed {\sf 36 \ Newtons}}[/tex]
Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
[tex]F=m \times a[/tex]
The mass of the wagon is 12 kilograms and the acceleration is 3 meters per square second.
m= 12 kg a= 3 m/s²Substitute the values into the formula.
[tex]F= 12 \ kg \times 3 \ m/s^2[/tex]
Multiply.
[tex]F= 36 \ kg*m/s^2[/tex]
1 kilogram meter per square second ( 1 kg*m/s²) is equal to 1 Newton (N)Our answer of 36 kg*m/s² is equal to 36 N[tex]F= 36 \ N[/tex]
The force required for the 12 kilogram wagon to accelerate at 3 meters per square second is 36 Newtons.

solar flares
gamma ray

energy released during
nuclear fusion
Answer:
1. Solar wind: a stream of plasma.
2. Coronal mass ejection: includes prominences and solar flares.
3. Gamma ray photon: energy released during nuclear fusion.
Explanation:
1. Solar wind: a stream of plasma i.e charged particles such as ions, protons, alpha, and electrons that continuously escape at high speed from the Sun because of the very hot plasma contained in the solar corona.
2. Coronal mass ejection: includes prominences and solar flares that flow outward into interplanetary space. Thus, it's a release of solar wind plasma and magnetic field from the outer atmosphere or corona of the sun.
Additionally, a solar prominence is also known as filament and it can be defined as a large, bright, dense cloud of luminous ionized gas such as hydrogen, sodium calcium, etc., that erupts (extends) from the surface of the sun. It can linger in the corona for a very long time, reaching hundreds of thousands of kilometers into the sun's atmosphere (space).
3. Gamma ray photon: energy released during nuclear fusion of radioactive isotopes such as cobalt-60 or cesium-137. It has the shortest wavelength and highest energy in the electromagnetic radiation spectrum.
An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.
At what distance from a 1.00*10^-5 C charge will the electric potential be 10000 V? (Unit = m)
Answer:
9.0 m
Explanation:
Applying
V = kq/r......................... Equation 1
Where V = Electric potential, q = charge, r = distance, k = Coulomb's constant.
make r the subject of the equation
r = kq/V................... Equation 2
From the question,
Given: q = 1.00×10⁻⁵ C, V = 10000 V
Constant: k = 9.0×10⁹ N⋅m²/C²
Substitute these values into equation 2
r = (9.0×10⁹×1.00×10⁻⁵)/10000
r = 9.0 m
Answer:
9.0

The armature of an ac generator is a circular coil with 50 turns and radius 2.30 cm. When the armature rotates at 350.0 rev/min, the amplitude of the emf in the coil is 20.0 V. What is the magnitude of the magnetic field (assumed to be uniform)
Answer:
B = 6.57 T
Explanation:
The amplitude of emf of an AC generator coil can be given by the following formula:
[tex]EMF = N\omega AB[/tex]
where,
EMF = amplitude of emf = 20 V
N = No. of turns = 50
ω = angular speed= (350 rev/min)(2π rad/1 rev)(1 min/60 s) = 36.65 rad/s
A = Cros-sectional area of coil = πr² = π(0.023 m)² = 1.66 x 10⁻³ m²
Therefore,
[tex]20\ V = (50)(36.65\ rad/s)(1.66\ x\ 10^{-3}\ m^2)B\\\\B = \frac{20\ V}{(50)(36.65\ rad/s)(1.66\ x\ 10^{-3}\ m^2)}[/tex]
B = 6.57 T

When light reflects off a rough surface, what happens to the image?
A. It's clear but inverted
B. It's clear and upright
C. It's blurry and inverted
D. No image is formed
Answer:
D. NO MAGE IS FORMEDExplanation:
#CARRY ON LEARNING#MARK BRAINLITSThe light reflects off a rough surface, what happens to the image is that will occurs No image is formed.
How to explain the reflection of light?Reflection of light happens when a ray of light strikes a reflective surface and returns to its original medium. This phenomenon allows us to see all bodies that do not produce their own light, called secondary sources of light or simply illuminated bodies.
Diffuse reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all.

Explanation:
A property of matter by which it remains at rest or in uniform motion in the same straight line unless acted upon by some external force.
Answer:
Inertia.
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
For example, the inertia of an object such as a shopping cart is greatly dependent or influenced by its mass; the higher quantity of matter in a shopping cart, the greater will be its tendency to continuously remain at rest.
If the effort distance = 8 meters and the resistance distance = 1/2 meter. How much force does this man have to apply to lift the 1 ton (2000 N) weight?
Answer:
Explanation:
Effort x effort distance = load x resistance distance
effort distance = 8 m ,
load = 2000N
resistance distance = 1/2 m = 0.5 m
Putting the values in the equation above
effort x 8m = 2000N x .5
effort = 2000 x 0.5 / 8
= 125 N
force required = 125 N .

5. What is the amount of work done when JoAnne throws a baseball 6.5 meters at a force of 40 newtons?
Answer:
W = 260 J
Explanation:
Work is defined by
W = F. d
Bold type indicates vectors,
W = F d cos θ
where tea is the angle between the force and the displacement, in this case the force is parallel to the displacement so the angle is zero and the
cos 0=1
let's calculate
W = 40 6.5
W = 260 J

El tren Lima la Orolla va a una velocidad de 10 km/h y de pronto aplica el freno por un derrumbe en la via. Si demora 18 segundos en detenerse ¿Qué distancia recorrerá hasta detenerse completamente?
Answer:
Distancia = 50.04 metros
Explanation:
Dados los siguientes datos;
Velocidad = 10 km/h
Tiempo = 18 segundos
Para encontrar la distancia;
Conversión:
10 km/h = 10 * 1000/3600 = 2.78 m/s
Distancia = velocidad * tiempo
Distancia = 2.78 * 18
Distancia = 50.04 metros
Por lo tanto, el tren viajaría 50.04 metros antes de detenerse por completo.

A hot, just-minted copper coin is placed in 101 g of water to cool. The
water temperature changes by 8.39°C and the temperature of the coin
changes by 68.0°C. What is the mass of the coin? Disregard any energy
transfer to the water's surroundings.
Answer:the specific heat is the measure of how much heat per unfit mass required to raise the temperature by 1 degrees Celsius.the formula is given as Q= cm T where
Q= the amount of heat added
C= specific heat of a substance
T= change in temperature in degrees Celsius
Q=(4186 j/kg degrees Celsius (.109 kg) (8.93- degrees Celsius)=4974.53J
Explanation:
The mass of the copper coin placed in 101g of water is 135.3g.
COLORIMETER:The mass of the copper coin can be calculated using the following expression:
Since; Q = mc∆T
Where;
Q = heat absorbed or releasedm = mass of substancec = specific heat capacity of substance∆T = change in temperaturemc∆T (water) = mc∆T (copper)
According to this question;
COPPER METAL:
m = ?c = 0.385 J/g°C∆T = 68°CWATER:
m = 101gc = 4.18 J/g°C∆T = 8.39°C101 × 4.18 × 8.39 = (0.385 × m × 68)
3542.09 = 26.18m
m = 3542.09 ÷ 26.18
m = 135.3g
Therefore, the mass of the copper coin placed in 101g of water is 135.3g.
