5 words to describe mass science
Answer:
Scientific Definition of Mass. Mass is the quantity of inertia (resistance to acceleration) possessed by an object or the proportion between force and acceleration referred to in Newton's Second Law of Motion (force equals mass times acceleration). In other words, the more mass an object has, the more force it takes to get it moving.

Objects fall near the surface of the earth with a constant downward acceleration of 10 m/s2 . At a certain instant an object is moving upward at 20 m/s. What is its velocity 2 sec later?
Answer:
After 2 seconds the velocity of the object is 0 m/s.
Explanation:
The velocity at 2 seconds later can be calculated as follows:
[tex] V_{f} = V_{0} - gt [/tex]
Where:
[tex]V_{f}[/tex]: is the velocity at 2 seconds
[tex]V_{0}[/tex]: is the initial velocity = 20 m/s
g: is the gravity = 10 m/s²
t: is the time = 2 s
Hence, the final velocity is:
[tex] V_{f} = V_{0} - gt = 20 m/s - 10 m/s^{2}*2 s = 0 m/s [/tex]
This value (0 m/s) means that the object has reached the maximum height.
Therefore, after 2 seconds the velocity of the object is 0 m/s.

When we get out of the bed on a very cold morning, we feel that the air of the room is cold. But when we come back after staying out for some time, we feel that the air of the same room is warmer. Why is this?
Answer:
This is because the air outside is always cooler than the air inside, so after staying outside your body adapts to the cold air, when you come back inside, the cold air is still in you which makes the room seem warmer.
A car speeds up from rest to some final velocity in some amount of time. If the time is doubled to reach the same final velocity, what
happens to the acceleration? Is this a proportional or inversely proportional relationship?
If the time is doubled to reach the same final velocity, then the acceleration will be half the acceleration before.
What is the rate of change?The rate of change of an object's velocity with respect to time is defined as acceleration. Vector quantities are accelerations.
Let's assume the final and the initial velocity of the object is v and u, respectively. Also, the time it takes is represented by t. Therefore, the acceleration can be written as,
a₁ = (v-u)/t
Now, if the time is doubled then the acceleration can be written as,
a₂ = (v-u)/2t
= (1/2) × [(v-u)/t]
= 0.5 × a₁
a₂ = 0.5a₁
Hence, If the time is doubled to reach the same final velocity, then the acceleration will be half the acceleration before.

A 4-kg plastic tank that has a volume of 0.18 m3 is filled with liquid water. Assuming the density of water is 1000 kg/m3, determine the weight of the combined system.
Answer:
weight= 1805.04 NExplanation:
In this problem we are expected to find the weight of the plastic tank and the weight of the equal volume of water
Given that
density of water = 1000 kg/m^3
volume of plastic tank is same as the volume of water= 0.18 m^3
we need to solve for the mass of the water
we know that density is = mass/volume
1000= mass/0.18
mass= 1000*0.18
mass= 180 kg
the total mass of the combined system is
4+180= 184 kg
the weight = mg (assuming g= 9.81 m/s^2)
weight = 184*9.81
weight= 1805.04 N

A racecar traveling at a velocity of 18.5 m/s, accelerates at a rate of 2.47 m/s2 and covers a distance of 79.78 m. Determine the final velocity of the racecar.
Answer:
The final velocity of the race car is 27.14 m/s
Explanation:
Given;
initial velocity of the race car, u = 18.5 m/s
acceleration of the race car, a = 2.47 m/s²
distance covered by the race car, s = 79.78 m
Apply the following kinematic equation to determine the final velocity of the race car.
v² = u² + 2as
v² = (18.5)² + 2(2.47)(79.78)
v² = 736.363
v = √736.363
v = 27.14 m/s
Therefore, the final velocity of the racecar is 27.14 m/s

90. An uranium nucleus (at rest) undergoes fission and splits into two fragments, one heavy and the other light. Which fragment is moving faster after the fission?
Answer:
Explanation:
No external force is acting on uranium nucleus so we can apply law of conservation of momentum . If M and m be the mass of bigger and smaller fragments respectively and V and v be their velocity after fission , Total momentum after fission = total momentum before fission
MV - mv = 0 , since the nucleus was at rest , its momentum before fission is zero . negative sign of mv is taken because smaller fragment will move in opposite direction to that of bigger fragment .
MV = mv
M / m = v / V
M > m
Hence,
v > V
So velocity of smaller fragment will be higher .

The weightlifter's internal store of energy decreased when he lifted the bar.
The bar's internal store of energy increased by a smaller amount.
Explain why.
Answer:
The energy returns to the weightlifter's muscles, where it is dissipated as heat.
Explanation:
The energy returns to the weightlifter's muscles, where it is dissipated as heat. As long as the weightlifter controls the weight's descent, their muscles are acting as an overdamped shock absorber, as if the weight were sitting on a piston containing very thick fluid, slowly compressing it downward (and slightly heating up the fluid in the process). Since muscles are complicated biological systems and not simple pistons, they require metabolic energy to maintain tension throughout the controlled descent, so the weightlifter feels like they're putting energy into the weight, even though the weight's gravitational potential energy is being converted into heat within the lifter's muscles.

(a) How far has the bicyclist traveled during the entire trip
Answer:
(a) She has traveled a total distance of 28958.04 m during the entire trip.
(b) Her average velocity for the trip is 6.12 m/s
Explanation:
Here is the complete question:
A bicyclist makes a trip that consists of three parts, each in the same direction (due north) along a straight road. During the first part, she rides for 26.8 minutes at an average speed of 7.57 m/s. During the second part, she rides for 42.4 minutes at an average speed of 3.17 m/s. Finally, during the third part, she rides for 9.69 minutes at an average speed of 15.0 m/s. (a) How far has the bicyclist traveled during the entire trip? (b) What is her average velocity for the trip?
Explanation:
(a) To determine how far the bicyclist has traveled during the entire trip, we will calculate the distance she covered in each part of the trip, and then sum up the distances to determine the total distance covered.
First, The distance covered in the first part of the tripDuring the first part, she rides for 26.8 minutes at an average speed of 7.57 m/s
That is,
Average speed, [tex]v[/tex] = 7.57 m/s
and time, [tex]t[/tex] = 26.8 minutes
Convert the time to seconds
∴ [tex]t[/tex] = 26.8 minutes = (26.8 × 60) secs = 1608 secs
[tex]Average speed = \frac{Distance }{ Time}[/tex]
Then, [tex]Distance = Average speed[/tex] × [tex]Time[/tex]
Hence, for the first part
[tex]Distance = 7.57[/tex] × [tex]1608[/tex]
[tex]Distance = 12172.56[/tex] m
This is the distance covered in the first part of the trip.
For the distance covered in the second part of the tripDuring the second part, she rides for 42.4 minutes at an average speed of 3.17 m/s
That is, Average speed, [tex]v[/tex] = 3.17 m/s
and time, [tex]t[/tex] = 42.4 minutes
Convert the time to seconds
∴ [tex]t[/tex] = 42.4 minutes = (42.4 × 60) secs = 2544 secs
From,
[tex]Distance = Average speed[/tex] × [tex]Time[/tex]
[tex]Distance = 3.17[/tex] × [tex]2544[/tex]
[tex]Distance = 8064.48[/tex] m
This is the distance covered in the second part of the trip.
For the distance covered in the third part of the tripDuring the third part, she rides for 9.69 minutes at an average speed of 15.0 m/s
That is, Average speed, [tex]v[/tex] = 15.0 m/s
and time, [tex]t[/tex] = 9.69 minutes
Convert the time to seconds
∴ [tex]t[/tex] = 9.69 minutes = (9.69 × 60) secs = 581.4 secs
From,
[tex]Distance = Average speed[/tex] × [tex]Time[/tex]
[tex]Distance = 15.0[/tex] × [tex]581.4[/tex]
[tex]Distance = 8721[/tex] m
This is the distance covered in the third part of the trip.
Now for the distance covered during the entire trip,
Total distance = distance covered in the first part of the trip + distance covered in the second part of the trip + distance covered in the third part of the trip
Hence,
Total distance = 12172 m + 8064.48 m + 8721 m
Total distance = 28958.04 m
Hence, she has traveled a total distance of 28958.04 m during the entire trip.
(b) For her average velocity for the trip
Average velocity is given by
[tex]Average velocity = \frac{Total distance traveled}{Total time}[/tex]
Total distance traveled = 28958.04 m
Total time = 1608 secs + 2544 secs + 581.4 secs
Total time = 4733.4 secs
Hence,
[tex]Average velocity = \frac{28958.04}{4733.4}[/tex]
Average velocity = 6.1178 m/s
Average velocity ≅ 6.12 m/s

a camel walks for 450 meters then hops on a bicycle and rides for 100 meters riding with a speed of 25 m/s in the same direction the average speed of the camel for the entire trip is 7 m/s what speed did the camel walk
Answer:
6.03 m/s
Explanation:
Average speed = total distance traveled/total time taken
7 = 450 + 100/total time
total time = 550/7 = 78.57 s
Speed of camel on the bicycle = distance/time
25 = 100/time
time = 100/25 = 4 s
Total time = 78.57 s
Time spent riding bicycle = 4 s
Time spent walking = total time - time spent riding bicycle
= 78.57 - 4 = 74.57 s
Speed of walking = distance walked/time spent walking
= 450/74.57
= 6.03 m/s
how could the student estimate the average speed in the first 8 hours
Answer:
use this formula
