Answer:
The answer is
55 miles/hrExplanation:
The velocity or speed of an object can be found by using the formula
[tex]velocity \: = \frac{distance}{time} [/tex]
From the question
time taken to travel = 10 hours
distance covered = 550 miles
Substitute the values into the above formula and solve for the velocity
That's
[tex]velocity = \frac{550}{10} [/tex]
We have the final answer as
55 miles/hrHope this helps you
When a basketball player jumps to make a shot, _____.
Answer:
i would like some more explanation i dont understand the question enough
Explanation:
Answer:
Its D.
Explanation:
"When a basketball player jumps to make a shot, _____.""A:the forces on the player’s feet and on the floor are both in the upward direction B:the action-reaction forces are unequal because they act on different objects C:the force with which he jumps is equal to the force with which he shoots the ball D:the downward force on the floor is equal to the upward force on his feet "the floor is flat so it wont be a bc the shoes or not flat and its not b bc how u saypost to jump up uk and its not c bc u need to jump u cant just hit your shot when u jump up u gotta make sure u aimed for the shot soIs it possible to have positive velocity and positive acceleration?
Explanation:
Yes. For example, when you press the gas pedal in a car, you accelerate in the same direction that you are moving in. So the velocity and acceleration have the same sign.
What is the displacement of the iguana between 0s and 5s?
Answer: the displacement is 8m and the distance traveled is also 8 meters
Explanation:
It travels from -2 to 6, a difference of positive 8, and since that was its initial starting point, displacement is 8m, distance traveled also happens to be 8m
Answer:
8 and 8 (No decimals needed) See attached! :)

3. An athlete swims from the north end to the south end of a 50.0 m pool
in 20.0 s and makes the return trip to the starting position in 22.0 s.
a. What is the average velocity for the first half of the swim?
b. What is the average velocity for the second half of the swim?
c. What is the average velocity for the roundtrip?
Answer:
a.2.5 m/s
b.2.27 m/s
c.2.385 m/s
Explanation:
velocity=displacement/time
a.50/20=2.5 m/s
b.50/22=2.27 m/s
c.average velocity=total velocity/2
=2.27+2.5/2
=4.77/2
=2.385 m/s

Why might a scientist use a physical model of a plant cell instead of studying
a cell directly?
A. A model can be used for things that are too simple to study
directly
B. A model can be used for things that are too large to study directly.
C. A model can be used for things that are too small to see clearly.
D. A model can be used for things that are too hot to handle easily.
Answer: I think it’s C.
Explanation:
The correct answer is C
Scientific Models are lay down processes or ideas toward achieving a specific goal. It can be mathematical in nature, or conceptual representation.
In most cases, scientific model are employed for complex findings or experiments. In this scenario, the plant cell is complex to study in the sense that the cells can not be seen with our naked eyes.
Therefore, the scientist will use a physical model of a plant cell instead of studying a cell directly because a model can be used for things that are too small to see clearly.
The correct answer is C

How long will your trip take if you travel 4000 m at an average speed of 8m/s
Answer:8.3mins
Explanation:
S=Vt
where V=average speed
S=4000m V=8m/s
4000=8×t
t=4000/8
t=500s
t=500/60
t=8.3min
500 sec
8 min 20 sec
Explanation:Hi there !
8 m ................ 1 s
4000 m ........ x s
x = 4000m×1s/8m = 500 sec = 8 min 20 sec
Good luck !

Room temperature air has a density of 1.2 g/cm3. A balloon filled with hydrogen has a density of 0.082 g/cm3, and a balloon filled with carbon dioxide has a density of 1.9 g/cm3. Predict what would happen if both balloons were dropped.
Explanation:
If both the balloons were dropped so the balloon filled with hydrogen had will rise up in the air because the density of hydrogen is less as compared to the density of air and the balloon filled with carbon dioxide will start to go down/sink, as the density of carbon dioxide is greater than air.

Explain what the interviewer meant when he said that genetic mutations are like misprints in a book.
Answer:
A publisher can misprint a book in several different ways. The publisher can miss words, make spelling errors, mix up paragraphs, or delete some text entirely. With such errors, the text will be inaccurate, and people reading that part will get confused. Mutations in genes happen similarly. At times, parts of the gene may change entirely, leading to altered products. There are many types of gene mutations, but all types of mutations can potentially affect the cell and its function.

Explanation:
Answer:
Solar-powered photovoltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business.

If a distance versus time graph is flat, what does that say about the velocity at that time?
Answer:
In either case, the curved line of changing slope is a sign of accelerated motion (i.e., changing velocity). Applying the principle of slope to the graph on the left, one would conclude that the object depicted by the graph is moving with a negative velocity (since the slope is negative ).

1. Do you think your memories can be altered? Explain
Answer:
Yes
Explanation:
I think our memories can be altered by emotions. If someone tells you something over and over and over again with strong emotion you will start to remember that more than the memory.
Emotions are very powerful and if you feel a certain emotion connected with a different memory I think that is stronger and can trick your brain into thinking that is the memory because of the strong emotion, even though the true memory was right, since it might not have as strong of mental emotion your brain will think that is the false memory because whatever is more memorable your brain will remember.

A gas has a pressure of 0.470 atm at 60.0°C. What is the pressure at standard temperature? Round your answer to the nearest thousandth
Answer:
P2=0.385atmExplanation:
step one:
Given that the temperature T1= 60 Celcius
we can convert this to kelvin by adding 273k to 60 Celcius
we have T1= 333k
pressure P1= 0.470 atm
step two:
we know that the standard temperature is T2= 273K
Applying the temperature and pressure relationship we have
P1/T1=P2/T2
substituting our given data we have
0.47/333=P2/273
cross multiply we have
P2= (0.47*273)/333
P2= 128.31/333
P2=0.385 atm
From fastest to slowest, rank the speeds of the balls 1 s after being thrown. Rank the speeds of the balls from fastest to slowest. To rank items as equivalent, overlap them. Three balls of different masses are thrown straight upward with initial speeds as indicated: PICTURE
rank speeds
rank acclerations
Explanation:
From the given figure,
Mass of ball A is 4.9 kg and its initial speed is 8 m/s.
Mass of ball B is 1.9 kg and its initial speed is 14 m/s.
Mass of ball C is 0.7 kg and its initial speed is 2 m/s.
We need to find the final speed of the balls 1 s after being thrown. They all are thrown upward under the action of gravity. The equation of motion is : v = u -gt, g = 10 m/s²
For ball A,
v = 8-10(1) = = -2 m/s (downward)
For B,
v = 14-10(1) = 4 m/s (upward)
For C,
v = 2-10(1) = -8 m/s (downward)
It means the ranking is B>A>C i.e. the speed of ball B is the most and that of C is least.
All the balls are moving under the action of gravity. It would mean that the acceleration for all balls is same i.e. 10 m/s²

Balanced forces acting on an object
O Always change the object's motion.
O Sometimes change the object's motion.
O Never change the object's motion.
O Are not related to motion.
Answer:
Balanced forces do not change the motion of an object. The motion of an object will not change if the forces pushing or pulling the object are balanced. An object that is sitting still will stay still if the forces acting on it are balanced
Explanation:
When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: ... a moving object continues to move at the same speed and in the same direction.
