What is the acceleration of a racing car if it's speed is increased uniformly from 44 m /s to 66 m / s over an 11 second period ?
Answer:
the acceleration of the race car is 2 m/s²
Explanation:
Given;
initial velocity of the race car, u = 44 m/s
final velocity of the race car, v = 66 m/s
time of motion of the race car, t = 11 s
The acceleration of the race car is calculated as;
[tex]a = \frac{v-u}{t} \\\\a = \frac{66-44}{11} \\\\a = 2 \ m/s^2[/tex]
Therefore, the acceleration of the race car is 2 m/s²

Describe how a magnetic field moves in a magnet. plz help!!
Answer:
In a permanent magnet, the magnetic field comes from the motion of the electrons inside the material, or, more precisely, from something called the electron spin. The electron spin is a bit like the Earth spinning on its axis. The magnetic field is a vector, the same way the electric field is.

What is hydrogens outer most energy level
Answer:
Students should realize that each atom in a group has the same number of electrons in its outermost energy level. For instance, hydrogen, lithium, sodium, and potassium all have 1 electron on their outer energy level. Let students know that these electrons in the outermost energy level are called valence electrons.

All music, _______ in the world, is from only ______ notes.
Answer:
All music in the world, is form only two notes and those notes are described below in detailed explanation.
Explanation:
In the chromatic scale, there are basically seven central musical notes, designated A, B, C, D, E, F, and G. They individual express a separate pitch or frequency. For illustration, the "central" A note has a pitch of 450 Hz, and the "common" B note has a pitch of 495 Hz.
Varieties Of Musical Notes You Require To Understand
Semibreve (Whole Note)
Minim (Half Note)
Crotchet (Quarter Note)
All music, listened to in the world, is from only twelve (12) notes.
A music can be defined as the systematic combination of an instrumental sound and human vocals, in order to produce harmonious tunes or sounds.
A note can be defined as a symbol which is used to denote a musical sound with respect to its pitch and duration.
Basically, all the music that are available and listened to in the world are typically produced from only twelve (12) notes.
This ultimately implies that, any musical piece that you may have come across in this world comprises only twelve (12) notes and these include:

What were the organic compounds Professor Wadhwa found and why are they important?
Answer:
Organic compounds are important because all living organisms contain carbon. They are the basic components of many of the cycles that drive the earth. For example, the carbon cycle that includes the exchange of carbon between plants and animals in photosynthesis and cellular respiration.
Not really understanding this, wouldn't mind some help. : )
Explanation:
Given
Mass (m) = 1200 kg
Acceleration (a) = 3 m/s²
Force (F) = ?
We know
F = m * a
= 1200 * 3
= 3600 Newton.
Therefore the force acting on the car is 3600 Newton.

Please help me please I need someone to help me with all this question 1) How do we calculate the momentum of a race car? What part of this changes during a collision? 2) What happening to the momentum of the car when they crash? 3) how does impulse factor into this? 4) what type of collision is it ( ideally) when cars crash into this SAFER barrier?
Answer:
Explanation:
1 ) Momentum of a race car = mass of car x velocity of car . During a collision , an external force acts on the car which changes the momentum of the car in the direction in which force acts .
2 )
The momentum of the car decreases as external force acts against the momentum . Sometimes when external force is very high , direction of momentum is reversed .
3 ) Impulse is force x time of action of force . Generally time of action of force in large collision is very small . so it is calculated very carefully .
Impulse = change in momentum .
4 ) The type of collision is inelastic . In this type of collision , car crashes into safer barrier , sticks to it . It does not rebound from the barrier . In case of elastic collision , rebound creates large impulse creating huge damage to the car .
