We're provided - mass ( m ) = 5 kg , initial velocity ( u ) = 10 m / s , final velocity ( v ) = 30 m / s , Time taken ( t ) = 20 sec and we're asked to find out the amount of force applied.Here , we'll use ' F = ma ' in order to find out the amount of force applied where ' F ' refers to Force applied , ' m' refers to mass of the body and ' a ' refers to acceleration.Since we aren't provided the acceleration , we're gonna use ' v - u / t ' where ' v ' refers to final velocity , ' u ' refers to initial velocity & ' t ' refers to time taken.[tex] \large{ \tt{✺ \: USING \: NEWTONS \: SECOND \: OF \: MOTION }}: [/tex]

An astronaut is said to be weightless when he/she travels in a satellite. Does it mean that the earth does not attract him/her
First of all, what a weight is? weight is m × g.. and when a person is in space then the force of gravity isn't acting on him or her, so yeah it will not have weight, but remember gravity is a very very low, now if a body has more mass, more gravity will act on it right? just imagine the mass of a person and that of earth.. now yes, earth will do exert a force on the astronaut but is negiligable.
The Hubble Space Telescope (HST) orbits 569 km above Earth's surface. If HST has a tangential speed of 7,750
m/s, how long is HST's orbital period? The radius of Earth is 6.38 x 106m. Make sure to use correct significant
figures.
Answer:
Mean radius of earth = 6.37E6 meters
Orbital radius = .569E6 meters
Total radius = (6.37 + .57) * 10^6 m = 6.94E6 m
P = S / t = 2 * pi * 6.94E6 / 7.75E3 sec = 5630 sec = 93.8 min
what is anti-matter made of
HERE'S YOUR ANSWER
Explanation:
Antimatter is a material composed of so-called antiparticles. It is believed that every particle we know of has an antimatter companion that is virtually identical to itself, but with the opposite charge. For example, an electron has a negative charge.

What is the constraint forces
Answer:
(1) Support
(2) Tension
(3) Reaction
The constraint forces are forces that occur in pairs such that the net force (effect) is zero
The details of the constraint forces are;
(1) The support force at the top of the swing acting upwards
(2) The tension in the swing rope acting upwards
(3) The (normal) reaction between the legs of the swing frame and the ground
Explanation:
The normal reaction is the force equal in magnitude and opposite in direction to the total weight force the swing and the person on the swing posses due to gravitational attraction which prevents the downward or sideways motion of the entire swing
- What will be the field strength from a 1.25* 10^-3 when measured 0.4m from the charge?
Answer:
Explanation:
I'm assuming your charge is in Coulombs so I will proceed that way. The formula for this electric field problem is
[tex]E=\frac{kQ}{r^2}[/tex] where k = 9.0 × 10⁹. Filling in:
[tex]E=\frac{(9.0*10^9)(1.25*10^{-3})}{.4^2}[/tex] gives us an electric field value of
7.0 × 10⁷ N/C
Tenemos un Cable de cobre de 1 km de longitud cuya sección es de 2 milímetros al cuadrado y queremos saber la resistencia que señalara el ohmetro , su temperatura es de 20°
Answer:
8.5 Ω
Explanation:
La resistencia de un material es directamente proporcional a su longitud e inversamente proporcional al área de la sección transversal.
La fórmula de la resistencia (R) viene dada por:
R = ρL/A
Donde ρ es la resistividad del material, L es la longitud del material y A es el área de la sección transversal del material.
Dado que:
L = 1 km = 1000 m, A = 2 mm² = 2 * 10⁻⁶ m², ρ (cobre) = 1.7 * 10⁻⁸ Ωm
Sustituyendo da:
R = 1,7 * 10⁻⁸ * 1000/2 * 10⁻⁶
R = 8.5 Ω
Kinetic energy is the _____ of motion.
Kinetic energy is the energy which a body possesses by virtue of being in motion. Thus, kinetic energy is the energy of motion.
What is kinetic energy?In physics, an object's kinetic energy is the energy it has as a result of its motion. It is defined as the amount of work required to accelerate a body of a given mass from rest to a given velocity. The standard unit of kinetic energy is the joule. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.
The body retains its kinetic energy after gaining it during acceleration unless its speed changes. The body does the same amount of work when slowing down from its current speed to rest.
Therefore, kinetic energy is the energy of motion.

Which of the following is not true about electric potential energy?
It depends on how much charge is moving through the field
It can be measured in joules
It can be measured in calories
It is a measure of how strong the electric field is only
Answer:
the second one
Explanation:
When a free positive charge q is accelerated by an electric field, such as shown in Figure 1, it is given kinetic energy. The process is analogous to an object being accelerated by a gravitational field. It is as if the charge is going down an electrical hill where its electric potential energy is converted to kinetic energy. Let us explore the work done on a charge q by the electric field in this process, so that we may develop a definition of electric potential energy.
The electrostatic or Coulomb force is conservative, which means that the work done on q is independent of the path taken. This is exactly analogous to the gravitational force in the absence of dissipative forces such as friction. When a force is conservative, it is possible to define a potential energy associated with the force, and it is usually easier to deal with the potential energy (because it depends only on position) than to calculate the work directly.

What is the momentum of an object with a mass of 50 kg travelling at 8 m/s?
Please answer ASAP
We know that,
p = mv
Where p is momentum,m is mass & v is velocity.From ques. we have;
mass = 50 kgVelocity = 8 m/sSo,
p = 50 × 8
p = 400 kg m/s
p = mv
Clearly, now just put the values
p = 50 × 8
p = 400 kg m/s

Alisa, a skateboarder, is riding down a hill. If Alisa and the skateboard are considered a single object, what forces are acting on her? Check all that apply.
Answer: gravity
normal force
friction
Explanation:
A force is refered to as the interaction which when unopposed, will lead to a change in an objects motion. The velocity of an object will be changed when force is applied.
Since Alisa s riding down a hill and she and the skateboard are considered to be a single object, then the forces that are acting on her include gravity, normal force and friction.

Along a horizontal snow-covered track, a sled, of mass m = 105 kg, slides by the action of a horizontal force of 230 N. The coefficient of friction between the sled and the snow is µ = 0.025.
Answer:
Explanation:
The only thing I can figure you need here is the accleration of the sled. The equation we need to find this is Newton's Second Law that says that sum of the forces acting on an object is equal to the object's mass times its acceleration. For us, that looks like this because of the friction working against the sled:
F - f = ma but of course it's much more involved than that simple equation! We have the F value as 230 N, and we have the mass as 105, but we do not have the frictional force, f, and we need it to solve for a in the above equation. We know that
f = μ[tex]F_n[/tex] where μ is the coefficient of friction, and [tex]F_n[/tex] is the normal force, aka weight of the object. We will use the coefficient of friction and find the weight in order to fill in for f:
[tex]F_n=mg[/tex] so
[tex]F_n=(105)(9.8)[/tex] so the weight of the sled is
[tex]F_n=[/tex] 1.0 × 10³ with the correct number of sig dig there. Now to find f:
f = (.025)(1.0 × 10³) so
f = 25 to the correct number of sig fig. Now on to our "real" equation:
F - f = ma and
230 - 25 = 105a. We have to do the subtraction first, round, and then divide since the rules for addition and subtraction are different from the rules for dividing and multiplying.
230 - 25 will round to the tens place giving us 210. Then
210 = 105a. 210 has 2 sig figs in it while 105 has 3, so we will divide and round to 2 sig fig:
a = 2.0 m/sec²
