Answer: b. The flow of air is neither toward the warm air mass nor toward the cold air mass.
A stationary front forms between two air masses. A stationary front results when the warm front or cold front air stops moving. This occurs due to the fact that warm front and cold front air masses being opposite to each other but neither of them are able to repel the other. This affects the climatic conditions of the region. The weather is often cloudy along a stationary front and also supported with fall of rain and snow especially if the air in the front is cold with low atmospheric pressure.
Therefore, along a stationary front the flow of air is neither toward the warm air mass nor toward the cold air mass.
A stationary front is formed when a cold air mass and a warm air mass meet, but neither is strong enough to displace the other. The air flow is generally neither towards the cold nor warm air mass, often resulting in prolonged cloudiness and precipitation
Along a stationary front, option b best describes what happens. Generally, stationary fronts occur when a cold air mass and a warm air mass meet, but neither is strong enough to move the other. As a result, the flow of air is typically neither toward the warm air mass nor toward the cold air mass. Instead, both air masses essentially stay where they are, often resulting in prolonged periods of cloudiness and precipitation in the area surrounding the front.

b 34.6 m/s
c 0 m/s
d 20 m/s
Vertical component = 40 m/s x sin(60) = 34.6 m/s
Answer: b. 34.6 m/s
The vertical component of velocity is approximately 34.64 m/s. Therefore option B is correct.
When an object is launched at an angle, its velocity can be divided into horizontal and vertical components. The vertical component is found by multiplying the initial velocity by the sine of the launch angle.
To find the vertical component of the velocity, we use trigonometric relationships based on the given launch angle of 60 degrees and initial velocity of 40 m/s.
The vertical component can be calculated as , where v is the initial velocity and is the launch angle.
Calculation:
Given:
Initialvelocity (v) = 40 m/s
Launch angle = 60 degrees
Vertical component:
In this case, with an initial velocity of 40 m/s and a launch angle of 60 degrees, the vertical component of velocity is approximately 34.64 m/s (option b).

b. 48.91 s
c. 48.910 s
d. 48.9 s
Answer:
Least precise recorded time is 48.9 seconds.
Explanation:
Here, we need to write the recorded time that is least precise. The given options are (a) 48.9107 s (b) 48.91 s (c) 48.910 s (d) 48.9 s. The precision in any measurement is defined as closeness in any measurement.
First option is most precise as it is precised to four decimal places. Second option is precised to two decimal places. Third option is precised to 3 decimal places. But in option fourth, the recorded time is precised to one decimal place.
Hence, the correct option is (d).
Answer:
Option A
Explanation:
Newton's third law : They have equal magnitude but directed in opposite direction.
The energy possess is 6,000,000 J
The kinetic energy is a energy by which an object can move and potential energy is a stored energy which depends upon the relative position of various parts of the body.
Given:
The mass of automobile is .
The velocity of the automobile is .
Write the formula to calculate the potential energy of the body.
Since the automobile is on ground so the height will be 0.
Write the formula to calculate the kinetic energy.
Substitute the value.

Answer:
6,000,000 J (6 million)
Explanation:
Refer to the equations for potential and kinetic energy.
Because the automobile is on the ground (it does not give a height above the ground, therefore we can assume that it is on the ground), height = 0. If you plug in 0 for h in the potential energy equation, we get PE = 0 J.
Therefore, all of the energy is kinetic. Plug in the given information into the kinetic energy equation. M = 1200 kg and v = 100 m/s
