>Explain whether life could exist on other
planets or moons in our solar system.
Answer:
The direct answer to the question "Can there be life..." is that there is potentially a non-zero possibility. Testing the null hypothesis, that there "cannot be life" is quite difficult. Evidence for and against both positions exists. However strong the arguments for life, space provides many harsh environments, yet we know deep in our oceans at hydro-thermal vents or in volcanic geysers there is life. Seeing volcanism on other worlds at least provides a necessary energy source. But the null hypothesis has a fatal flaw. We know of one location where there is life, and we discover over and over again that its conditions are not very special in the Universe. The famous Drake equation goes much further, to single out intelligent life that still exists today and wishes to communicate. But in very sad news for the null hypothesis, even it is non-zero.

A person is walking from the front of a train toward the back of a train at a constant velocity of 3 mph. The train is moving forward at a velocity of 20 mph. What is the velocity of the walking person relative to the land outside the train?
Explanation:
This is the Galilean transformation.
V' = V - U where want to find V' in the primed frame of reference.
The primed frame is moving at speed U = -20 relative to the train.
V = -3 is the speed of the person in the frame of the train.
Then V' = -3 - (-20) = 17 mph relative to the land outside the train.

Texting and driving is a dangerous act
and is illegal in many areas. Suppose a driver takes 3.5 seconds to send a text. Travelling at 95 km/h, how far in meters did the vehicle travel while the driver was distracted? (Hint: How many seconds are in an hour?
How many meters are in a km?)
Answer:
s = 92.36 m
Explanation:
The distance covered by an object moving with uniform speed is given by the following formula:
s = vt
where,
s = distance covered by car during the time when driver was distracted in texting = ?
v = uniform speed of car = (95 km/h)(1 h/3600 s)(1000 m/1 km) = 26.39 m/s
t = time taken by the driver for texting = 3.5 s
Therefore, using these values in equation, we get:
s = (26.39 m/s)(3.5 s)
s = 92.36 m
Boojho saw a cracker burst at night at a distance from his house. He heard
the sound of the cracker a little later after seeing the cracker burst. Give the
reason for the delay in hearing the sound.
Answer:
The primary reason of seeing the cracker burst and hearing the sound later is because the speed of sound and light. Speed of light is in the vicinity of 3*10^8m,/ sec while the speed of sound is at a distance of 332m/sec. It is similar to lightning that strikes before the sound.

What is the acceleration of a 2,000 kg truck if it takes a 5,500 N force to move it forward?
Explanation:
Newton's second law:
F = ma
5500 N = (2000 kg) a
a = 2.75 m/s²
A satellite in space has a mass of 252 kg. The engines on it provide a net force of 6.81×10-3 N. How long will it take for this satellite to go from rest to a final velocity of 262 m/s forward?
Acceleration = (force) / (mass)
Acceleration = (6.81 x 10⁻³ N) / (252 kg)
Acceleration = 2.70 x 10⁻⁵ m/s²
Time = (change in v) / (acceleration)
Time = (262 m/s) / (2.70 x 10⁻⁵ m/s²)
Time = 9,703,704 seconds
That's 2,695.5 hours , or 112.3 mean solar Earth days .

During a sunny afternoon, the sun suddenly seems much less bright than usual. The daylight seems much less intense, as if there is a dense cloud cover, but there’s no clouds in the sky. After about half an hour, everything seems normal again. Which claim about the temporary decrease in light can be supported by the evidence?
Answer:
D). A sudden change in temperature increased the density of the atmosphere.
Explanation:
The claim that can be made and supported with evidence regarding the temporary decrease in light would be 'a sudden change in temperature will increase the density of the atmosphere.' As the temperature increases, the molecules in the atmosphere begin to move fastly which causes a decrease in atmosphere density while it increases with the fall in temperature. As a result, the intensity of sunlight gets affected due to molecules being heavier and floating in the atmosphere. Thus, option D is the correct answer.
Answer: Its the atmosphere

Express 3 x 10-9s in milliseconds
Answer:
3 × 10 to the power minus 6 milliseconds
When we convert 3 x 10⁻⁹ s into milliseconds it would be 3 x 10⁻⁶milliseconds
What are significant figures?In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.
If a number describing the result of a measurement (such as length, pressure, volume, or mass) includes more digits than the number of digits permitted by the measurement resolution, only the digits allowed by the measurement resolution can be significant figures.
As given in the problem we have to convert 3 x 10⁻⁹ s into milliseconds
1 second = 1×10³ milliseconds
3 x 10⁻⁹ seconds = (3 x 10⁻⁹) × (1×10³ )
= 3 x 10⁻⁶milliseconds
Thus, 3 x 10⁻⁹ s converted into milliseconds it would be 3 x 10⁻⁶ milliseconds

Eric has a mass of 19.0 kg on the earth. What is Eric's weight on earth? What is Eric's weight on Mars? where the acceleration of gravity is approximately 0.381 of that of Earth's? ________.
Answer:
Weight on Earth = We = 186.2 N
Weight on Mars = Wm = 70.94 N
Explanation:
The weight of an object is defined as the force applied on the object by the gravitational field. The magnitude of weight is given by the following formula:
W = mg
were,
W= Weight of Eric
m = mass of Eric
g = acceleration due to gravity
ON EARTH:
W = We = Eric's Weight on Earth = ?
m = Eric's Mass on Earth = 19 kg
ge = acceleration due to gravity on Earth = 9.8 m/s²
Therefore,
We = (19 kg)(9.8 m/s²)
We = 186.2 N
ON MARS:
W = Wm = Eric's Weight on Mars = ?
m = Eric's Mass on Mars = 19 kg
gm = acceleration due to gravity on Mars = 0.381(ge) = (0.381)9.8 m/s² = 3.733 m/s²
Therefore,
Wm = (19 kg)(3.733 m/s²)
Wm = 70.94 N

A hotwheels car is rolled from 0.72 meters to the 1.51 meter mark. What is the displacement of the toy car?
(do not enter units into your answer in canvas)
Answer:
it is d]
Explanation:
The displacement of the toy car will be 0.79 meters.
What is displacement?The shortest route between two points is displacement.
It is a vector quantity to be displaced. This suggests that it has a size and a direction, and that it may be thought of as an arrow pointing from one place to another.
Distance is never less than displacement; it must always be more than or equal to it.
Displacement can be zero if the starting and end point are the same.
According to the question, the Hot wheel car rolled from 0.72 meters to the 1.51-meter mark.
So, the displacement of the toy car will be :
⇒1.51-0.72
=0.79
Hence, the total displacement will be 0.79 meters.
