A rocket has a mass of 80,000 kg and accelerates at a rate of 35 m/s2. Calculate the force that provides this acceleration,
Explanation:
Given
Mass(M) = 80,000 kg
Acceleration (a) = 35 m/s²
Force (F) = ?
We know we have the formula
F = m * a
= 80000 * 35
= 2800000
= 2.8 * 10 ^ 6 N
The force is 2.8 * 10 ^ 6 N.
Hope it will help :)❤
If a rocket has a mass of 80,000 kg and accelerates at a rate of 35 m/s2. then the force that provides this acceleration would be 2800000 Newtons.
What is Newton's second law?Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
The mathematical expression for Newton's second law is as follows,
F = m*a
As given in the problem we have to find the force that provides the acceleration of 35 meters / second², if the rocket has a mass of 80,000 kg,
The force acting on the rocket = 80,000 × 35
= 2800000 Newtons
Thus, the force acting on the rocket would be 2800000 Newtons.

The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
Answer:
True.
Explanation:
The given statement is true that the law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
According to this law, the forces between two masses can be calculated by the product of their masses and divided by the square of the distance between them. Mathematically, it can be written as :
[tex]F=\dfrac{Gm_1m_2}{r^2}[/tex]
G is universal gravitational constant
Hence, the given statement is true.
When electricity moves through a metal wire, the wire is
A. A resistor
B. A conductor
C. an insulator
D. a power supply
When electricity moves through a metal wire, the wire is option B. A conductor.
What is a Conductor?Conductors are materials that allow electricity to flow easily through them. An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow and causes resistance.The flow of electricity through a wire is the flow of electrons. An electron is a negatively charged subatomic particle. In electrical conductors, the flow of electricity results from the movement of electrons from one atom to the next.To learn more about conductors, refer to: https://brainly.com/question/27533161

Rutherford's model of atoms describes the atom as a tiny, dense particle which contains a positively charged nucleus with electrons which are negative charged moving in orbitals.
What is Rutherford's model?Rutherford's model of atoms described the atom as a tiny, dense, positively charged core particle which is called a nucleus, in which nearly all the mass of the atom is concentrated, around within the nucleus which the light, negative constituents, called electrons, circulate at some specific distance, much like the planets which are revolving around the Sun.
During the Rutherford's experiment, the alpha particles are bombarded on the thin piece of gold foil. The alpha particles were expected to pass easily through this gold foil.

help plss .. Two bicyclists are accelerating forward in a straight line, and Biker 1 has less
mass than Biker 2. If the net force on the bikers is the same, which statement
describes their acceleration?
Explanation:
Remember Newton's Second Law.
[tex]F=ma[/tex]
If the force acting on both bikers is the same, we can look at the relationship between acceleration and mass.
If Biker 1 has a mass of 10kg and Biker 2 has a mass of 20kg, and both are being acted upon by a force of 100 N, let's see what that looks like. [tex]100 = 10*a_1 \rightarrow a_1 = 100/10 = 10[/tex]
[tex]100 = 20 *a_2 \rightarrow a_2 = 100/20 = 5[/tex]
So, given the same force, an object with GREATER mass will have less acceleration.

A 0.20 kg baseball is traveling at 40 m/s toward the batter. The ball is hit by the bat with a force of 200N, and is
now headed toward the pitcher at 25 m/s. How long was the bat in contact with the ball?
Answer:
Time, t = 0.015 seconds.
Explanation:
Given the following data;
Mass, m = 0.2kg
Force, F = 200N
Initial velocity, u = 40m/s
Final velocity, v = 25m/s
To find the time;
Ft = m(v - u)
Time, t = m(v - u)/f
Substituting into the equation, we have;
Time, t = 0.2(25 - 40)/200
Time, t = 0.2(-15)/200
Time, t = 3/200
Time, t = 0.015 seconds.
Note: We ignored the negative sign because time can't be negative.

13. Harry used the energy stored in his muscles to cycle up a hill. What happened to this energy when he reached the top?
A. The energy stored in Harry's musclesbwas destroyed.
B. The energy was returned to Harry's muscles
C. Kinetic energy changed to potential energy.
D. Potential energy changed to kinetic energy.
Answer:
C. Kinetic energy changed to potential energy.
Explanation:
The kinetic energy is converted to potential energy when he reaches the top of the hill.
As with every system, energy is neither created nor destroyed but transformed from one form to another.
This is from the law of conservation of energy.
Kinetic energy is produced when Harry moves the up the hill. As he reaches the top of the hill and comes to rest, potential energy is formed.
Potential energy is the energy due to the position of a body.
A 136 kg defensive lineman is about to tackle a 100 kg quarterback. Right before
impact, the lineman is moving north at 6.0 m/s and the quarterback is moving
north at 1.0 m/s. Determine the speed and direction of the two players
immediately after the tackle.
Answer:
3.88 m/s North
Explanation:
We are given that
[tex]m_1=136kg[/tex]
[tex]m_2=100 kg[/tex]
[tex]v_1=6 m/s[/tex]
[tex]v_2=1m/s[/tex]
We have to find the speed and direction of the two players
immediately after the tackle.
Using linear conservation of momentum
[tex]m_1v_1+m_2v_2=(m_1+m_2)v[/tex]
Substitute the values
[tex]136\times 6+100\times 1=(136+100)v[/tex]
[tex]916=236v[/tex]
[tex]v=\frac{916}{236}[/tex]
[tex]v=3.88m/s[/tex]
Direction of the two players immediately after the tackle is North.
