Answer: 37 Celsius and 310.15 K
Explanation:
C/5 = (F-32)/9 = (98.6-32)/9 = 66.6/9 = 7.4
C = 7.4 * 5 = 37 so the temperature is 37 Celsius
K = C + 273.15 = 37 + 273.15 = 310.15 K

Use Newton’s First Law of Motion and the concept of inertia to explain what happens to a person in a head-on car accident who is not wearing a seat belt. How does wearing a seat belt help?
Answer:
Newtons first law of motion explains what happens in a car crash because it basically states that the passenger will continue to travel at the same velocity until an unbalanced force acts on he or she. The force that will act upon he or she would be the window, so you should always wear a seat belt!
Explanation:
According to Newtons first law of motion, a passenger tends to continue in the state of uniform motion even after the accident which causes the passenger to move forward.
According to the Newtons first law of motion, an object will continue in a state of rest or uniform motion unless it is acted upon by an external force. This is also known as the law of inertia.
While in a car undergoing uniform motion and suddenly the car is involved in an accident which causes the vehicle stop abruptly, a person suddenly moves forward because of the tendency to continue in the former state of uniform motion according to Newtons first law.
A seat belt helps to prevent the person from suddenly moving forward in a way that may lead to injury as a result of the accident.

If the voltage of a circuit is 6V, and the power is 4W, what is its resistance?
Answer:
9 ohms
Explanation:
P = V²/R
R = v²/p = 6²/4 = 36/4 = 9 ohms.
The resistance is 9 Ohm.
To find the resistance, we need to know about the power in term of resistance and voltage.
What is the value of power in terms of resistance and voltage?We know that power=work/timeElectrostatics work is given as voltage ×charge. So, power=(Voltage×charge)/timeAgain, charge/time is given as current. So, power = Voltage×currentFrom Ohm's law, we know that current=voltage/resistance. So, power= voltage ²/resistance. What is the resistance, if power is 4W and voltage is 6V?Resistance in term of power and voltage is given as Resistance= voltage ²/powerSo, resistance=6²/4=36/4= 9 OhmThus, we can conclude that the resistance is 9 Ohm.

someone help pls. Two students, Mia and Peter, leave school to meet at the local coffee shop. Peter decides to jog to the coffee shop, but also stops at a flower shop along the way. Mia decides to walk from school directly to the coffee shop. They arrive at the coffee shop at the same time, 30 minutes after they leave school.
Answer:
1) The distance further it takes Peter to arrive at the Coffee shop than Mia is 1.24 km
2) Mia's average speed is 6.00 km/hour
Peter's average speed is 8.48 km/hour
4) Mia's average velocity = Peter's average velocity = 6.00 km/hour
Explanation:
The given information from the diagram are;
The distance Peter jogs from school to the flower shop = 2.00 km
The distance Peter jogs from the Flower shop to the Coffee shop = 2.24 km.
The distance Mia walks from school directly to the Coffee shop = 3.00 km
The time it takes both Peter and Mia to arrive at the coffee shop = 30 minutes = 0.5 hour
1) The total distance Peter travels from school to the Coffee shop = 2.00 km + 2.24 km = 4.24 km
The distance Mia travels from school to the Coffee shop = 3.00 km
The distance further it takes Peter to arrive at the Coffee shop than Mia = 4.24 km - 3.00 km = 1.24 km
The distance further it takes Peter to arrive at the Coffee shop than Mia = 1.24 km
2) [tex]Average \ speed = \dfrac{Total \ distance \ traveled}{Total \ time \ taken \ in \ the \ journey}[/tex]
[tex]Therefore, \ Mia's \ average \ speed = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour[/tex]
Mia's average speed = 6.00 km/hour
[tex]Peter's \ average \ speed = \dfrac{4.24 \ km}{0.5 \ hour}= 8.48 \ km/hour[/tex]
Peter's average speed = 8.48 km/hour
4) [tex]Average \ velocicty = \dfrac{Displacement }{Time \ taken}[/tex]
The displacement from the School to the Coffee shop is 3.00 km for both Mia and Peter
The time it takes both Peter and Mia to arrive at the Coffee shop from the school is 30 minutes = 0.5 hour
[tex]Therefore, \ Mia's \ average \ velocity = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour[/tex]
Mia's average velocity = 6.00 km/hour
[tex]Peter's \ average \ velocity = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour[/tex]
Therefore, Peter's average velocity is also = 6.00 km/hour
Ana kicks a stationary 0.2kg soccer ball. The ball leaves her foot at a speed of 20 m/s.
A.What impulse was delivered to the ball?
B. The ball experience 40N of force during the kick. How long were the ball and foot in contact?
Answer:a. 24 kg m/s
b. 3/5s
Explanation:
a.impulse is the change in momentum so at first the momentum is zero because the ball was at rest and the final momentum is 1.2kg*20m/s=24 kg m/s
so the impulse would be (24-0) kg m/s=24 kg m/s
b. so the impulse equation is impulse is force *delts time
so 24 kg m/s=40N*t
t=24 kg m/s /40N=3/5 s

An object horizontally dragged across the surface by a 100 N force acting parallel to the surface . Find out the amount of work done by force in moving the object through a distance of 8 m
Answer:
800J
Explanation:
Given data
Force= 100N
Distance moved= 8m
The expression for the work done is
WD= Force* distance
substitute
WD= 100*8
WD= 800Joules
Hence the work done is 800J

]A net force of 15 N is applied to a cart with a mass of 2.1 kg.How long will it take the cart to travel 2.8 m, starting from rest? Acceleration=7.14m/s²
we will use one of the kinematic equations :
d = u*t+0.5*a*t²
in which : d : distance
u : initial velocity
a : acceleration
t : time
after substitution :
initial velocity = 0 m/s (from rest)
2.8 = 0*t+0.5*7.14*t²
2.8 = 3.57*t²
t² = 0.7843
after square root
t = 0.885615 s

What is longitudinal wave?
A sound wave is called a longitudinal wave because compressions and rarefactions in the air produce it.
The air particles vibrate parallel to the direction of propagation.
A longitudinal wave consists of a repeating pattern of compressions and rarefactions.
Thus, the wavelength is commonly measured as the distance from one compression to the next adjacent compression or the distance from one rarefaction to the next adjacent rarefaction.
Longitudinal waves move through a medium from the point of the disturbance in the form of compressions (where particles of the medium are bunched together) followed by rarefactions (where particles of the medium are farther apart).
In longitudinal waves, the distance from one compression to the next is the wavelength.
Therefore,
In longitudinal wave the wavelength is longer.

Answer:
Option C, a pan heated to 100°C
Explanation:
The pan on the burner will be in direct contact of the heat released by burner and hence the pan will receive the direct flow of heat from the burner.
However, the water is the pan will be heated by the heat transferred from the pan to the water in it. Water will not receive heat directly from the burner.
Hence, option C is correct

C or 3 a pan heated to 100°CExplanation:

What is transmission of sound?
Sound is transmitted through gases, plasma or blood, and liquids as longitudinal waves, also called compression waves. It requires a medium to propagate. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves.
For example, when you flick the rim of a glass, the glass will vibrate imperceptibly. These vibrations move through the air and strike the ear drum of anyone within hearing range (click here to find out 'How Our Ears Hear'). In fact, these vibrations, or sound waves, can move through any medium: gas, liquid or solid.

A ball is thrown horizontally from the roof of a building 50. m tall and lands
45 m from the base. What was the ball's initial speed?
Answer:7.92 m/s
Explanation:
A ball is thrown horizontally from the roof of a building 50. m tall and lands 45 m from the base then the ball's initial speed is 14.10 m/s
What is speed?The rate of change of position of an object in any direction is called speed. Speed is scalar quantity.
speed = distance/time
s=d/t
Where,
s is the speed in m/sec
d is the distance travaled in m
t is the time taken in sec
Given that in the question ball travel a height from building of 50 m to a distance 45 m from the base so total distance travelled is given as 45 m.
Body is travelling downward under the influence of gravity.
Using equation of motion under gravity,
y = ut + ½gt² , where u = 0 m/s in y direction and
y = ½gt²
t² = 2y / g
t² = 2*50/9.8
t = 3.19 sec
ball's initial speed in x direction is given as
u = 45/3.19
u= 14.10 m/sec.
The balls initial speed is given as 14.10 m/sec.
