Answer:
5.6 m/s
Explanation:
The acceleration of any possible is the ratio of the velocity of the particle with respect to the time the particle takes in moving. It is mathematically represented as
a = v/t, with m/s² as it's unit, where
v = velocity in m/s
t = time taken in seconds
a = acceleration in m/s²
From the explanation above, we were given in the question that, the speed is 112 m/s and the time if took is 20 seconds, thus, the acceleration is
a = 112/20
a = 5.6 m/s²
Therefore, the magnitude of the acceleration is 5.6 m/s²
How long would it take Jesse with an acceleration of -2.50 m/s^2 to bring his bicycle with an initial velocity of 13.5 m/s to a complete stop?
a.6.1 s
b.3.7 s
c.12.1 s
D.5.4 s
Answer:
use first equation of motion v=u+at..v is 0..since we have to take him to rest and u is 13.5
Explanation:
u = 13.5 m/s
a = - 2.5 m/s^2
v = u + at
0 = 13.5 - 2.5 * t
t (time to reach a complete halt) = 5.4 sec

>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.

Answer:
0 m/s²
Explanation:
Velocity is the slope of the position vs time graph. The graph is linear, so the velocity is constant. Since the velocity is constant, the acceleration is 0.
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 .

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

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

A seesaw pivots as shown in below. What is the net torque about the pivot point?
With explanation please
I GIVE 25 POINTS
Answer:
2.3 Nm clockwise
Explanation:
Take counterclockwise to be positive and clockwise to be negative.
∑τ = (3 N) (2.5 m) − (7 N) (1.4 m)
∑τ = 7.5 Nm − 9.8 Nm
∑τ = -2.3 Nm
The net torque is 2.3 Nm clockwise.

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

Describe all of the forces acting on the ice cream in the root beer float. Relate these forces to the fact that the ice cream is floating
Answer: Sample Response: The root beer exerts a force on all sides of the ice cream. These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward. The ice cream floats because the buoyant force is greater than the weight of the ice cream.
