an object is moving forward with a constant velocity. which statement about this object must be true?
Answers
Answer:
• Its acceleration is zero
Explanation:
from definition of acceleration:
[tex]{ \rm{acceleration = \frac{change \: in \: velocity}{time} }} \\ \\ { \rm{acceleration = \frac{ \delta \: (velocity)}{time} }}[/tex]
• since velocity is constant, change in velocity is zero
[tex]{ \boxed{ \rm{ \delta \: (velocity) = 0}}}[/tex]
• therefore:

heated in identical beakers over identical Bunsen burners. The red liquid
shows a dramatically faster increase in temperature. Which of these is the
most likely explanation for this? *
O A) The red liquid has a greater mass.
O B) The blue liquid has a smaller mass.
O C) The red liquid has a greater specific heat.
OD) The red liquid has a smaller specific heat
Answers
When a substance has smaller specific heat it needs less heat to shows changes in it hence making the option D correct.

Based on Newton’s third law of motion, will a tennis ball go farther if it hits a tennis racquet that is still or one that is in motion?
OPTIONS:
A.
One that is still because it will absorb all of the force of the ball.
B.
One that is still because that will have a greater impact on the trajectory.
C.
One that is in motion because both the ball and the racquet will contribute momentum.
D.
One that is in motion because the racquet’s force will cancel the ball’s force out.
Answers
Answer:
c
Explanation:
because if a tennis ball hit a tennis racket still it would not go anywhere. with the tennis ball hitting the moving racket it will go further
One that is in motion because both the ball and the racquet will contribute momentum.
Thus, option (c) is correct.
Newton's third law of motion states that for every action, there is an equal and opposite reaction.
When the tennis ball hits a tennis racquet in motion, both the ball and the racquet will exert forces on each other in opposite directions.
This interaction will result in a transfer of momentum from the racquet to the ball and vice versa, potentially giving the ball a greater momentum and therefore potentially causing it to go farther.
Thus, option (c) is correct.

11. A roller coaster car is moving slowly up a long ramp to the very top of the roller coaster. It goes over the top and starts down a steep slope and it picks up speed rapidly as it rolls down an almost vertical slope. Four seconds later, at the bottom of the steep slope, its velocity is 28 m/s. The average acceleration during those 4 seconds was 6 m/s2 . What was the initial velocity of the roller coaster car as it started down the slope?
Answers
Answer:
a = (v2 - v1) / t
a t = v2 - v1
v1 = v2 - a t
v1 = 28 m/s - 6 m/s^2 * 4 s = 4 m/s

What is the initial velocity of a moose who
accelerates uniformly at 1.5 m/s/s for 5 seconds and
finishes with a velocity of 7 m/s?
Answers
Answer:
- 0.5 m/s
Explanation:
(1) Acceleration = change in velocity / time
(2) Change in velocity = (Final velocity - Initial velocity)
We know:
acceleration = 1.5 m/s/s
time = 5 seconds
final velocity = 7 m/s
x = initial velocity)
1.5 = ( 7 - x ) / 5
1.5 x 5 = ( 7 - x )
7.5 = 7 - x
x = -0.5 m/s
You can check the answer by plugging in the values to equation (1).

The table contains the planets in our solar system in order of their average distance from the Sun and their corresponding diameters. The first step in creating a model of the solar system is to scale these large diameters into smaller, more manageable numbers. Eventually, we’ll represent these numbers using circles drawn on paper. MercuryVenusEarthMarsJupiterSaturnUranusNeptune Diameter (km)487912,10412,7566792142,984120,53651,11849,528 Scaled Diameter (cm) 3.51.9 The ratio between Earth’s actual diameter and its scaled diameter can be used to find the scaled diameter of the other planets. Earth’s diameter of 12,756 kilometers is scaled to 3.5 centimeters as shown in the table. Now let’s find the scaled diameter of Mars as an example. Using the calculations shown, Mars’s diameter of 6,792 would be scaled to 1.9 centimeters. d × 12,756 = 6,792 × 3.5 d = 1.9 cm Use this same process to complete the table with the scaled diameters of the other planets. Round each answer to the tenths place. If you need additional math help, visit the Proportions section of the Math Review.

The scaled diameters of the missing planets are listed below:
Mercury 1.4 cm
Venus 3.3 cm
Mars 1.9 cm
Jupiter 39.2 cm
Saturn 33.1 cm
Uranus 14.0 cm
Neptune 13.6 cm
How to determine the scaled diameters of a planet
In this question we must use conversion factor to calculate the scaled diameters by means of the following direct relationship:
d = k · D (1)
Where:
D - Real diameter, in kilometers.d - Scaled diameter, in centimeters.k - Conversion factor, in centimeters per kilometer.The conversion factor is found by using the real and scaled diameter of the Earth:
k = 3.5 cm/12,756 km
k = 7/25512 cm/km
Then, we determine the scaled diameters of the rest of planets:
Mercury 1.4 cm
Venus 3.3 cm
Mars 1.9 cm
Jupiter 39.2 cm
Saturn 33.1 cm
Uranus 14.0 cm
Neptune 13.6 cm
Remark
The statement reports a table with numerous mistakes, the correct table is shown below:
Planet Diameter (km) Scaled Diameter (cm)
