Which of these units results when a distance of 35 m is multiplied by a force of 27 n, and then divided by a time of 5s? a newtom n is kg * m/s2 in si base units?

Answers

Answer:

SI unit for Joule per second is $(kg m^(2) )/(s^(2) )$ .

Explanation:

When a distance of 35 m is multiplied by a force of 27 N.

Force × distance = 27 N × 35 m = 945 Joule

945 Joule = 945 $(kg m)/(s^(2) ) * m$

945 joule = 945 $(kg m^(2) )/(s^(2) )$

This is SI unit for force multiplied by distance.

The above quantity is divided by 5 s.

$(945)/(5) (Joule)/(s)$ = 189 $(kg m^(2) )/(s^(3) )$

SI unit for Joule per second is $(kg m^(2) )/(s^(2) )$ .

Answer:

$(F * d)/(t) = 189 (kg m^2)/(s^3)$

Explanation:

Here first we multiplied the force with the distance so we have

F = 27 N

distance = 35 m

so the product is given as

$F* d = 27 N * 35 m$

$F* d = 945 N m$

now we have to divide it by time

so we have

$(F * d)/(t) = (945)/(5)$

$(F * d)/(t) = 189 Nm/s$

so it is

$(F * d)/(t) = 189 (kg m^2)/(s^3)$

A welding torch produces a flame by burning acetylene fuel in the presence of oxygen. This flame is used to melt a metal. Which energy transformation represents this process?

Answers

Answer

Chemical energy in to thermal energy

Explanation

When acetylene fuel is burning in presence of oxygen, we have chemical process taking place. The torch is used to heat metal to its kindling temperature in oxy-fuel cutting. The steam of gas is then trained on the metal burning it into a metal oxide that flows out of the spout.

So the energy transformation represents this process is Chemical energy into thermal energy

The correct answer for the question that is being presented above is this one: "Chemical energy turns into thermal energy. " A welding torch produces a flame by burning acetylene fuel in the presence of oxygen. This flame is used to melt a metal.

Here are the following choices:
A. Chemical energy turns into thermal energy.
B. Kinetic energy turns into potential energy.
C. Thermal energy turns into electromagnetic energy.
D. Potential energy turns into chemical energy.

What has to be different to allow refraction to occur?a. the medium
b. the light
c. the wave
d. the speed

Answers

a. the medium

For refraction to occur, there has to be change from one medium to another. For example rays of light would refract as the travel from air to water.

Using information about natural laws, explain why some car crashes produce minor injuries and others produce catastrophic injuries.

Answers

The larger the mass and the speed, the larger the force it would produce if it crashes something. Some car crashes produce minor injuries because maybe this car is small and runs at very slow speed which would mean less force when in impact with another. However, if a big truck crashes, it is expected to produce a larger force causing catastrophic injuries.

The car crash in which the car is moving at higher speed will cause catastrophic injuries whereas the car moving at smaller speed will cause minor injuries. This is due to the law of inertia of the bodies.

Explanation:

The inertia of a body is defined as the resistance of the body towards any change in its current state of rest or motion. The body does not want to change its state and this resistance of the body is directly proportional to the mass of the body.

According to the law of inertia, a body continues to be in its state of rest or motion until and unless an external force acts on the body.

A car moving at a higher speed and having a higher mass is considered to have higher inertia of motion and therefore when it crashes, it experiences a very high stopping force and due to this, the injuries caused in the car crash will be very catastrophic.

Whereas, if the same car is moving at a lower speed, the inertia of motion of the car will be less and when this car crashes, it will experience a smaller force and comes to rest. Due to this, the injuries caused in the crash will be minor.

Thus, The car crash in which the car is moving at higher speed will cause catastrophic injuries whereas the car moving at smaller speed will cause minor injuries. This is due to the law of inertia of the bodies.

The average distance from the sun to Pluto is approximately 6.10 time 10^9 km. How long does it take light from the sun (384,000 km/s) to reach Pluto?

Answers

From the information as given in the question, the transit time
for light from the sun would be

   (6.1 x 10⁹ km) / (3.84 x 10³ km/sec) = 15,885 seconds (rounded).
   (4.4 hours) .
==============================

-- A better figure for Pluto's average distance from the sun is 5.874 x 10⁹ km.

-- " 384,000 km/sec " is about 28% too high for the speed of light.
    A much better figure is 300,000 km/sec.

Using these numbers, the transit time is

   (5.874 x 10⁹ km) / (3 x 10⁵ km/sec) = 19,580 seconds
   (5.4 hours)
