A car moves at the constant speed of 20 m/s along a straight track for 12 seconds. Calculate how far it travels in meters in this time.
The distance traveled by car with a constant speed of 20m/s is equal to 240m.
What is speed?The speed of an object can be defined as the distance traveled by the object in a definite time interval. The speed is a scalar quantity as it carries only the magnitude and does not have any direction.
The speed can be calculated from the ratio of the distance traveled by the object to the time taken to cover that distance.
The speed equation for an object can be written as follows:
Speed = distance /time taken
Distance = Speed × time
Given, the speed of the car = 20 m/s
The total time taken by car to travel the distance = 12 sec
The distance traveled by car = 20 × 12 = 240 m.
Therefore, the car will travel a distance of 240 meters in a given time.

can you tell Which body part does not help in the perception and production of sound in humans?
ears, lungs, mouth or vocal cords
which is not?
Lungs do not help in the perception and production of sound in humans.
What are lungs?Gaseous exchange occurs during inhalation and exhale during breathing. Main components of the human respiratory system include the nose, mouth, throat, larynx, trachea, bronchi, and lungs.
In humans and other vertebrates, the primary organs for respiration are the lungs. They are situated in the thoracic cavity of the chest, on either side of the heart. The lungs are spongy, anatomically speaking, with a total surface area that ranges from 50 to 75 square meters.
The lungs' main job is to make it easier for gases to move from the blood into the air. It's interesting to note that the right lung is significantly larger and heavier than the left.
Hence, lungs do not help in the perception and production of sound in humans.

.
Answer in units of m/
Answer:
5.45 m/s
Explanation:
Given:
Δx = 2.08 m
v₀ₓ = v₀ cos 44°
aₓ = 0 m/s²
Δx = v₀ₓ t + ½ aₓ t²
2.08 m = (v₀ cos 44°) t + ½ (0 m/s²) t²
2.89 = v₀ t
Given:
Δy = 0.63 m
v₀ᵧ = v₀ sin 44°
aᵧ = -9.81 m/s²
Δy = v₀ᵧ t + ½ aᵧ t²
0.63 m = (v₀ sin 44°) t + ½ (-9.81 m/s²) t²
0.63 = 0.695 v₀ t − 4.905 t²
0.63 = 0.695 (2.89) − 4.905 t²
t = 0.530
v₀ = 5.45 m/s

1) A football player kicks a ball at an angle of 30 and gives it a velocity of 15m/s.
A) What was the time of flight?
B) How far horizontally does the ball land?
C) How high does the ball reach?
Answer:
A) 1.53s
B) 19.8m
C) 2.869m
Explanation:
A) The time of flight for a projectile can be calculated using the formula:
t = 2μsinθ/g
Where; u = velocity
θ = angle
g = acceleration due to gravity (9.8m/s^2)
t = 2 × 15 × sin 30°/9.8
t = 30sin30°/9.8
t = 30 × 0.5/9.8
t = 15/9.8
t = 1.53s
B) The horizontal range (distance) for a projectile can be calculated using the formula:
Range = u²sin2θ/ g
Range = 15² sin 2 × 30 / 9.8
Range = 225 sin 60/9.8
Range = 225 × 0.8660/9.8
Range = 194.855/9.8
Range = 19.8m
C) The maximum height for a projectile can be calculated using the formula:
h = u²sin²θ/2g
h = 15² (sin 30)² / 2 × 9.8
h = 225 × 0.25 / 19.6
h = 56.25/19.6
h = 2.869m
The speed of
a bus rs 72km/hr. Convert it into
si system dimensionally
Answer:
Speed = 20 m/s
Explanation:
The speed of a bus is 72 km/h
The SI unit of speed is m/s
We need to convert it into m/s
We know that,
1 km = 1000 m
1 h = 3600 s
It means,
[tex]s=72\ \dfrac{km}{h}\\\\=\dfrac{72\times 1000\ m}{3600\ s}\\\\=20\ m/s[/tex]
So, the speed of the bus is 20 m/s.

In a 350-m race, runner A starts from rest and accelerates at 1.6 m/s^2 for the first 30 m and then runs at constant speed. Runner B starts from rest and accelerates at 2.0 m/s^2 for the first 30 m and then runs at constant speed. Runner A befins running as soon as the race begins but B first takes a nap to rest up. What is the longest nap that B can take and still not lose the race?
Answer:
B can take 0.64 sec for the longest nap .
Explanation:
Given that,
Total distance = 350 m
Acceleration of A = 1.6 m/s²
Distance = 30 m
Acceleration of B = 2.0 m/s²
We need to calculate the time for A
Using equation of motion
[tex]s=ut+\dfrac{1}{2}at_{A}^2[/tex]
Put the value in the equation
[tex]30=0+\dfrac{1}{2}\times1.6\times t_{A}^2[/tex]
[tex]t_{A}=\sqrt{\dfrac{30\times2}{1.6}}[/tex]
[tex]t_{A}=6.12\ sec[/tex]
We need to calculate the time for B
Using equation of motion
[tex]s=ut+\dfrac{1}{2}at_{B}^2[/tex]
Put the value in the equation
[tex]30=0+\dfrac{1}{2}\times2.0\times t_{B}^2[/tex]
[tex]t_{B}=\sqrt{\dfrac{30\times2}{2.0}}[/tex]
[tex]t_{B}=5.48\ sec[/tex]
We need to calculate the time for longest nap
Using formula for difference of time
[tex]t'=t_{A}-t_{B}[/tex]
[tex]t'=6.12-5.48[/tex]
[tex]t'=0.64\ s[/tex]
Hence, B can take 0.64 sec for the longest nap .
how can we calculate the e.m.f of the battery?.
Explanation:
The emf is equal to the work done on the charge per unit charge (ϵ=dWdq) when there is no current flowing. Since the unit for work is the joule and the unit for charge is the coulomb, the unit for emf is the volt (1V=1J/C).
Answer:
The EMF or electromotive force is the energy supplied by a battery or a cell per coulomb (Q) of charge passing through it. The magnitude of emf is equal to V (potential difference) across the cell terminals when there is no current flowing through the circuit. (byjus)

Alice and Marge are studying the properties of matter. The girls placed some an iron nail in a beaker containing water. Iron is a solid metal at room temperature. Iron is a shiny and malleable; it can be formed into shapes like the nails the girls used. Iron will turn reddish-brown in the presence of air or water as it rusts. Iron is a good conductor of electricity and heat. After 48 hours, the girls checked the nail in the water and compared it to the nail they left on the lab bench. Here is a photo of their results.
Based on the girls' experiment, what is a chemical property of iron?
Answer:
When substances made of iron are exposed to oxygen and moisture (water), rusting takes place. Rusting removes a layer of material from the surface and makes the substance weak. Rusting is a chemical change.
Answer:
B) Iron rusts in water
Explanation:
Physical property is defined as the property of a substance which becomes evident during physical changes. Example: Melting point , electrical conductivity, malleability,
Chemical property is defined as the property of a substance which becomes evident during chemical changes. Example: Reactivity with other substances
Rust is hydrated ferric oxide .
Corrosion of iron is called as rusting. Rust is hydrated ferric oxide .
Thus rusting of iron is a chemical property.
