tony walks at an average speed of 70 m/min from his home to his school.If the distance between his home and the school is 2100 , how much time does it take for tony to walk to school
Answers
It takes 30 minutes for Tony to get to school.
2100 divided by 70 is 30, which would represent the amount of minutes.
Also he is walking very fast to be getting 70 in a minute.

Why does the North star not move but the other stars move
Answers
Answer:
it's the star in the center of the star field
Explanation:
Why Doesn't Polaris Move? Polaris is very distant from Earth, and located in a position very near Earth's north celestial pole. ... Polaris is the star in the center of the star field; it shows essentially no movement. Earth's axis points almost directly to Polaris, so this star is observed to show the least movement

What is the momentum of a 1, 500 kg car traveling at 3m/s?
67,500 kgm/s
67.5 kgm/s
4.5 kgm/s
4,500 kgm/s
Answers
========================================
Work Shown:
To find the momentum, we multiply the mass and the velocity.
m = mass = 1500 kg
v = velocity = 3 m/s
p = momentum
p = m*v
p = (1500 kg)*(3 m/s)
p = (1500*3) kg m/s
p = 4500 kg m/s
The momentum of an object is the product of its mass and velocity. Thus momentum of the car with 1500 kg and velocity of 3 m/s is 4500 kg m/s.
What is momentum?Momentum is a physical quantity that measure the ability to keep the force which make an object moves faster. Momentum like force is a vector quantity and is characterized with magnitude and direction.
Momentum is the product of velocity and its mass. Hence as the mass or velocity increases, momentum also increases. Increase in momentum makes the object moves faster.
Given mass of car = 1500 Kg
velocity = 3 m/s
momentum = velocity × mass
= 1500 Kg × 3 m/s
= 4500 Kg m/s.
Therefore, the momentum of the car is 4500 kg m/s.

A 5kg box rests on a table. a 3 kg box rests on top of the 5 kg box. what is the normal force from the table?
a. 19.6 n
b. 29.4 n
c. 49 n
d. 78.4 n
Answers
==> The total mass resting on the table is (5 kg + 3 kg) = 8 kg.
==> The total weight of that mass is (8 kg) x (9.8 m/s) = 78.4 newtons
==> The boxes are stacked. So the table doesn't know if the weight on it is coming from one box, 2 boxes, 3 boxes, or 100 boxes in a stack. The table only knows that there is a downward force of 78.4 newtons on it.
==> The table stands in a Physics classroom, and it soaks up everything it hears there. It knows that every action produces an equal and opposite reaction, and that forces always occur in pairs.
Ever since the day it was only a pile of lumber out behind the hardware store in the rain, the table has known that in order to maintain the good reputation of tables all over the world, it must resist the weight of anything placed upon it with an identical upward force. This is the normal thing for all good tables to do, up to the ultimate structural limit of their materials and construction, and it is known as the "normal force".
So the table in your question provides a normal force of 78.4 newtons. (d)
Engineers at the Space Centre must determine the net force needed for a rockets engine to achieve an acceleration of 70 m/s2. Assume the rocket is in outer space with no gravitational or other forces acting on it. If the mass of the rocket is 45 000 kg, what force is required to be produced by the rocket engines?
Answers
Answer:
3,150,000N
Explanation:
According to Newton's second law;
F = mass * acceleration
Given
Mass = 45000kg
acceleration = 70m/s^2
Substitute
F = 45000 * 70
F = 3,150,000N
Hence the force required to be produced by the rocket engines is 3,150,000N
Answer:
3,150,000 Newtons
Explanation:
F=M*A
F=45,000kg times (*) 70 m/s squared
F=3,150,000N (newtons)

Two masses oscillating together with each of their time period as ,'T'
To find↷New time period ,'T'Answer↷Option B
Time period is independent of mass so it will remain same irrespective of the mass on the spring so the new time period would be the exact same as the previous one.Solution↷we know that,
The time period of a mass 'm' on a spring of spring constant 'k' can be strategize by the following equation :
[tex] \huge \rightarrow \: T \: = 2π \sqrt{ \frac{m}{k} } [/tex]
m⇢mass of the body [kg]k⇢spring constant [Nm^-1]According to the question,
The new mass would be 2mThe new spring constant would be 2kso,
The new time period would be
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{2m}{2k} } [/tex]
