Medium and heavy duty vehicles require a better braking option hence they ought to have an exhaust brake.

A brake is used to slow down or stop an automobile. When the brake is applied, the speed of the automobile continues to decrease until it comes to a complete halt.

Friction brakes are apt for light vehicles that may not have the tendency to overheat. However, heavy duty vehicles may overheat often and do require an exhaust brake.The exhaust brake is most fitted for heavy duty vehicles and diesel engines.

Answer:

Normal, Gravitational, Applied, Friction, and Tension

Explanation:

Because the sled is on the ground, or rather because it is on the earth, it will have a force of gravity, or its weight, pulling it down.

There is a normal force because the sled is not moving into the ground, so there needs to be a force pushing on the sled from the ground. Additionally, Newton's 3rd law states that for every action there is an equal but opposite reaction, if it's in equilibrium or not moving.

There will be an applied force since the child is pulling the sled and is applying a force to do so.

There will be a friction force that is pulling the sled opposite the direction it is moving, since it is on the ground that is presumably not fricitonless.

There will be a tension force pulling on the sled by the rope. However there is also a tension force pulling on the child's hand by the rope, meaning that these are internal forces and essentially balance out, but they are still there.

There is no air resistance force, or very little of it, since the object is not falling.

Answer:

number of moles of gas.

Explanation:

We know the formula

So

if magnitude of charge is increased the force between them also increased.

And if the distance between them is decreased them also the force will be increased.

So Force increases

Weight of soccer ball

Weight of watermelon

As the watermelon has more weight, it will hit the ground first.

This object should not change its direction of motion because despite its velocity it will be still moving to the right.

The equation describe the velocity of an object and how this velocity changes depending on time.

The equation does not describe the direction of motion. Due to this, it is expected the direction is the same and does not change.

The induced emf is found as -0.0531 V. When the flux coupling with a conductor or coil changes, electromotive Force, or EMF, is said to be induced.

Emf is the production of a potential difference in a coil as a result of changes in the magnetic flux passing through it.

From Lenz law,the the induced EMF is found as;

[tex]\rm e=- \frac{\triangle \phi _B}{\triangle t } \\\\\rm e=- \frac{A\triangle B}{\triangle t } \\\\ e= -\frac{\pi r^2(0-1.10)}{0.15} \\\\ e=-0.0531 \ V[/tex]

Let β = v / c          

proper time Δt'  is measured in a frame at the same place in a given frame - the proper time is measured in spaceship II moving at .28 c

a) spaceship I is moving at (.6 - .28) c = .32 c relative to proper time

Δt = Δt' / (1 - β^2)^1/2      as measured by students in ship I

Δt = 50 / (1 - .32^2)^1/2 = 52.8 m        measured by students

Answer: young's modulus

Explanation: A very rigid material—one that stretches or compresses only slightly under large forces—has a large value of young's modulus .

Based on the calculations, the acceleration of this wagon along the ground is equal to: D. 3.60 m/s².

Given the following data:

Mass = 10 kg.

Angle = 35°

Force = 44 Newton.

In accordance with Newton's Second Law of Motion, the net force acting on this wagon is equal to the horizontal component of the force that is parallel to the slope:

F = macosθ

Substituting the given parameters into the formula, we have;

44 = 10 × a × cos35

44 = 10a × 0.8192

44 = 8.192a

a = 44/8.192

a = 3.60 m/s²

Answer:

a large elliptical galaxy

Explanation:

Climate change is the reason for a lot of factors such as:

Heat-trapping Greenhouse Gases And The Earth's Climate

Greenhouse Gases

Reflectivity or Absorption of the Sun's Energy

Changes in the Earth's Orbit and Rotation

Variations in Solar Activity

Changes in the Earth's Reflectivity

Volcanic Activity

There's a lot more that I could list, but hopefully this will do.

Answer:

The earth's axis of rotation is tilted 66.5 degrees with respect to its orbital plane around the sun and its axis of rotation is inclined 23.5 degrees from the perpendicular, with respect to this plane. The tilt of the earth affects the angle between the sun beam and the normal over a surface.

Earth orbits at an angle, so half the year, the Northern Hemisphere is tilted toward the Sun — this is summer in the Northern Hemisphere, and winter in the Southern Hemisphere. The other half of the year, the Northern Hemisphere is tilted away from the Sun, creating winter in the north and summer in the south.

When the Earth's axis is tilted toward the sun for the Northern Hemisphere, the people in the Northern Hemisphere experience summer, while at the same time, the Southern Hemisphere is tilted away from the sun and the people there experience winter.

The Northern Hemisphere receives the maximum intensity of the sun's rays, while the angle of sunlight decreases in the Southern Hemisphere.

When the sun's rays strike Earth's surface near the equator, the incoming solar radiation is more direct (nearly perpendicular or closer to a 90˚ angle). Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures.

Wy= -mgcos21=-1150*9.81*cos8.7=-11151.69N

(negative because weight points downwards)

This item will finally boost up down the inclined plane due to the presence of an unbalanced pressure. it's far the parallel element of the pressure of gravity that reasons this acceleration. The parallel aspect of the force of gravity is the net force.

The y-issue of Vector B is contrary to the 40o perspective. while finding additives through drawing a right triangle across the given attitude, you want to put within the symptoms explicitly. In this case, the y-thing points up and so is wonderful.

For the maximum element, we will maintain weigh and weight immediately with the aid of the use of weighing as a verb and weight as a noun, with a smattering of exceptions for records and grades and blankets. Our advice: take consolation wherein you may. Because of this, an item's mass may be measured indirectly through its weight, and so, for regular purposes, weighing (the usage of a weighing scale) is a completely suited manner of measuring mass. Further, stability measures mass in a roundabout way by way of comparing the load of the measured item to that of an item(s) of recognized mass.

Answer:

D. they transfer thermal energy due to convection

In a building, air moves due to currents caused by temperature differences. They transfer thermal energy due to convection. this statement best describes these currents. Hence option D is correct.

Temperature is a physical quantity which measures hotness and coldness of a body. Temperature measures the degree of vibration of molecule in a body. Temperature is measured in centigrade (°C), Fahrenheit (°F) and Kelvin (K) in which Kelvin (K) is a SI unit of temperature. Absolute scale of temperature means Kelvin scale of temperature. relation between Kelvin(K) and centigrade (°C), °C= K - 273.15 from equation, 273.15 K means 0 °C, which is freezing point of water (ice). when we give temperature to the body, its molecule or atom absorbs thermal energy and vibrate about their mean position. Amplitude of vibration get increases as we go on increasing temperature and for higher temperature force of attraction between molecules gets weaker. Hence for higher temperature, due to weaken the force of attraction between molecule, solid goes into liquid state. and further increase in temperature liquid goes into gaseous state.

Hence option D is correct.
