1. A car travels along a straight road to the east for 100 meters in 4 seconds, then go the west for 50 meters in 1 second.
find the
a. Distance
b. Displacement
c. Time elapsed
Answer:
a.Distance = 150 m
b. Displacement = 50 m
Time lapsed = 5 seconds
Explanation:
a. Distance is the change in the position of an object.
The distance covered by the car = 100 + 50
= 150 m
b. Since displacement is a vector quantity,
Displacement of the car = 100 - 50
= 50 m due east
c. Time elapsed is the time taken for the motion of the car starting from when its starts to when it stops.
Thus, the time elapsed = 4 + 1
= 5 seconds
Mr. Rossi's car, stopped at the traffic lights, is hit by that of Mr. Bianchi. Then later in court, claims that he was traveling at 50 km / h, but Mr. Rossi
tthinks that mr. Bianchi was going much faster. After the collision the two cars got stuck and from the tracks on the asphalt it was possible to establish that, immediately after the collision, they were traveling at 30 km / h. Mr. Bianchi drove a car with a mass of 800 kg and Rossi a car with a mass of 1400 kg.
Does Bianchi tell the truth?

Answer:
23N
Explanation:
Answer:
9.3N
Explanation:
Fgrav = m • g = 14.7 N (g is 9.8 m/s/s)
a = v2 / R = (4 • Fgrav)/1 = 16 m/s/s
Fnet = m • a = 1.5 kg •16 m/s/s = 24 N, down
Fnet = Fgrav + Ftens, so
Ftens = Fnet - Fgrav
Ftens = 24 N - 14.7 N = 9.3 N
there is a metal ball and ring set that is specially made so that at room temperature at the ball fits through the ring However when the ball is heated it gets stuck and cannot fit through anymore .why
Answer: Most objects expand when they take in heat for example get a metal sphere and put it next to a blow torch it would expand just enough to not fit in the ring anymore, but when it cools down it will go back to its original size releasing the energy

A mass on a spring oscillates with a frequency of 0.1 Hz. The mass is 10 kg. What is the spring constant of the spring?
Answer:
3.94784176044N/m
Explanation:
The period of a spring is found using the formula T=2π[tex]\sqrt{\frac{m}{k} }[/tex], where m is the mass and k is the spring constant.
The period can also be found using the formula T=[tex]\frac{1}{f}[/tex], where f is the frequency.
T=T
∴2π[tex]\sqrt{\frac{m}{k} }[/tex]=[tex]\frac{1}{f}[/tex]
2π[tex]\sqrt{10/k}[/tex]=1/0.1
[tex]\sqrt{10/k}[/tex]=10/2π
10/k=1.59154943092²
10/2.53302959106=k
k=3.94784176044N/m

What is the resistance to this unbalanced force in football?
Answer:
Newton's first law of motion states that an object's motion will not change unless an unbalanced force acts on the object. ... The football player in the photo above is in motion. He will stay in motion unless players on the other team exert an unbalanced force against him.

And air rifle pellet of mass 2 g Is fired into a block of modelling clay mounted on a model railway track. The trunk and modelling clay have a mass of 0.1 kg the truck moves off after the pellet hits the modelling clay with an initial velocity of 0.8 m/s. State the momentum of the pallet just before it hits the modelling clay
Answer:
0.0816 kgm/s
Explanation:
From the question,
Momentum of the pellet just before it hits the modelling clay is = (mass of the pellet+ mass of the truck clay)×initial velocity of pellet.
P =(M+m)u...................... Equation 1
Where P = initial momentum of the pellet, m = mass of the pellet, u = initial speed of the pillet, M = mass of the truck
Given: m = 2 g = 2/1000 kg = 0.002 kg, u = 0.8 m/s, M = 0.1 kg
Substitute these values into equation 1
P = (0.002+0.1)0.8
P = (0.102)0.8
P = 0.0816 kgm/s

Question 17 of 25
Which term describes the transfer of energy from a hot object to a cooler
one?
A. Pressure
B. Density
C. Temperature
D. Heat
Answer:
D
Explanation:
heat is an energy that transfers from a hot body to cold body
D. Heat
What is heat?Heat is the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object.
Such energy transfer can occur in three ways: radiation, conduction, and convection.
As heat is a form of energy, and therefore the SI unit of heat is also joules (J) which are defined as the amount of energy needed to raise the temperature of a given mass by one degree.
Heat is the transfer of energy from a warmer object to a cooler object.
For example, a lighted match (higher temperature object) will transfer heat to a large pan filled with lukewarm water (lower temperature object).
Therefore,
The term describes the transfer of energy from a hot object to a cooler one is Heat.

Complete question is;
Describe how α-radiation is similar to β-radiation?
Answer:
Explained below
Explanation:
The similarity between both alpha radiation and beta radiation is that in both cases, they both show deflection when they go through electric and magnetic fields. Although alpha deflects towards the negative plate while bets deflects towards the positive plate.
Secondly they both have high speeds. Just that alpha is from the helium nucleus while beta is from electrons.

bus? *
Answer:
Mass of bus = 6,818.18 kg (Approx.)
Explanation:
Given:
Velocity = 22 m/s
Momentum = 150,000 kg-m/s
Find:
Mass of bus
Computation:
Mass = Momentum / Velocity
Mass of bus = 150,000 / 22
Mass of bus = 6,818.18 kg (Approx.)
Objects 1 and 2 attract each other with a electrostatic force of 36.0 units. If the charge of Object 1 is doubled, then the new electrostatic force will be units.
If the charge on the object is doubled then the new electrostatic force is 72 units.
What does the term "electrostatic force" mean?Non-contact forces, such as electrostatic forces, pull or push on objects without actually making contact with them. When certain materials are rubbed together, a phenomenon known as "charge" can be transferred from one surface to another. Uncharged items are pulled by charged objects, which in turn may push or pull against other charged ones.
Let q and Q represent the charges on objects 1 and 2, respectively.
Charge Q is separated from charge q by a distance r, and their electrostatic attraction is given by:
F = kqQ/r²
where k is Coulomb's constant
According to the question:
F = 36 units
⇒ kqQ/r² = 36 units
Now, the charge on object 2 is doubled, so it now acquires a 2Q charge.
So the new electrostatic force will be:
F' = kq(2Q)/r²
F' = 2kqQ/r²
F' = 2F = 2×36
F' = 72 units

Newton determined that there is a direct relationship between force and mass. Your weight equals your mass multiplied by the acceleration due to gravity. FALSE 8. A 10-kg object has greater acceleration due to gravity than a 5-kg object.
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object
