An object moves through space with balanced forces acting on it. Which statement
best describes the speed and direction of the object as long as the forces acting on it
remain balanced?
A. The speed and direction of the object will both change.
B. The speed and direction of the object will remain constanti
C. The speed will change, but the direction will remain constant.
D. The speed will remain constant but the direction will change
Answer:
B
Explanation:
Newton's first law of motion states that every object will continue in a state of rest or uniform motion in a straight line unless a resultant force acts on it
balanced force means resultant force is 0N
this means that the speed will not change as it uniform and the direction will not change because it will continue at the same speed in a statight line and direction

in 4 seconds, a cheetah can run 112 meters. How fast does this cheetah have to be running? A: 448 m/s || B: 28 m/s || C: 56 m/s || D: 36 m/s
Answer:
B: 28m/s
Explanation:
Use the speed formula
Speed =distance / time
Answer:
[tex]\boxed {\boxed {\sf B. \ 28 \ m/s}}[/tex]
Explanation:
If we want to know how fast the cheetah is running, we need to calculate its speed. This is the rate at which an object moves and the formula is distance divided by time.
[tex]s=\frac{d}{t}[/tex]
The cheetah ran 112 meters in 4 seconds.
d= 112 m t= 4 sSubstitute the values into the formula.
[tex]s=\frac{112 \ m}{ 4\ s}[/tex]
Divide.
[tex]s= 28 \ m/s[/tex]
The cheetah's speed is 28 meters per second and choice B is correct.

Justin mixed two cups of lemon juice and two cups of sugar with a gallon of water in a pitcher. What happened to the lemon juice, sugar, and water?
Answer:
The correct answer is - Lemon juice hydrolyzes sugar and dissolves it faster and creates a solution.
Explanation:
When mixing lemon juice and sugar in water are mixed together, the lemon juice dissolves the sugar faster as it has citric acid that hydrolyzes sucrose molecules of sugar in glucose and fructose.
This mixing of all three lemon juice, water, and sugar form a solution. Here in this solution, water is solvent, and sugar and lemon juice are solutes. The quantity of all three determined the nature of the solution if it will be acidic or more diluted.
The graph shows the layers of Earth's atmosphere. Which statement best describes the relationship between temperature and altitude in the atmosphere?
A. The relationship between temperature and altitude is variable and unpredictable.
B. Overall, the temperature of the atmosphere increases with altitude.
C. The relationship between temperature and altitude is different in each zone of the atmosphere.
D. Temperature decreases with altitude until the stratosphere is reached, and then it increases from there.
Answer:
The best statement which describe this is actually:
D. Temperature decreases with altitude until the stratosphere is reached, and then it increases from there.
Explanation:
From the graph shown, it could be seen that, temperature decrease with height. The higher the height, the lower the temperature. For example, from the graph, when the height was around 50 km, the temperature was within the range of -10⁰C to 0⁰C. On the other hand, when the height increases around 78 km, the temperature decreases to the range of to -70 ⁰C to -80⁰C

for every 1000 joules or useful energy output, the heater wastes 100 joules, find the input energy of the heater.
Answer:
the Input Energy is 1,100 J
Explanation:
Given;
useful energy, = 1000 J
energy wasted, = 100 J
The total or input energy is given as;
Input Energy = useful energy + energy wasted
Input Energy = 1000 J + 100 J
Input Energy = 1,100 J
Therefore, the Input Energy is 1,100 J

Sadie rides her bike 1600 m East and then turns around and goes 800 m
West. What is her displacement?
Answer:
(1600 m east) + (800 m west) = (800m east)
Her displacement is 800 m east.
Explanation:
Displacement is the distance and direction between the starting point and ending point,regardless of the route traveled between them.
Draw a circuit that uses the resistors listed below as well as a 12V battery source. For your circuit, determine (a) the total resistance, (b) the total current, and (c) the total voltage over the entire system.
Answer: hello your questions lacks the required resistor values therefore i will provide a general answer using an example
answer : a) 14 ohms b) 0.86 amps c) 10.32 V
Explanation:
Assuming the resistors are : 3 ohms , 4 ohms and 5 ohms
Voltage source = 12V
Assuming that the Resistors are in series
a) Determine Total resistance
Req = R1 + R2 + R3
= 3 + 4 + 5 = 14 ohms
b) Total current
Ieq = V / Req
= 12 / 14 = 0.86 amps
c) The Total Voltage over the entire system
Vt = ∑ Voltage drops
= ( 0.86 * 3 ) + ( 0.86 * 4 ) + ( 0.86 * 5 )
= 10.32 V

Answer:
4.Given:
m=1000kg
a=(3m/s)^2
F=m×a
=1000×3
=3000N
5.Given:
m=50kg
a=(5m/s)^2
F=m×a
=50×5
=250N
6. Given
F=250N
a=(5m/s)^2
m=?
F=m×a
250N=m×(5m/s)^2
m×(5m/s)^2=250N
m=250N÷(5m/s)^2
m=50kg

What is the speed of light?The speed of light, also known as the velocity of light, is a fundamental constant of nature and is one of the most well-known physical quantities. It is defined as the speed at which electromagnetic radiation (light) travels through a vacuum, which has a constant value of 299,792,458 meters per second (m/s).
This speed is considered to be the fastest that anything can travel in the universe, and it is a critical component in many physical and biological processes. The speed of light is used in a wide range of scientific and technological fields, including optics, electronics, astronomy, and quantum mechanics. It is considered to be a universal constant and does not change with time, distance, or the medium through which it travels.

Explanation:
A particle is accelerated uniformly from rest, so that after 10 seconds it has achieved a speed of 15 m/s. Find its acceleration.
Answer:
1.5 m/s²
Explanation:
Applying,
a = (v-u)/t ...................... Equation 1
Where a = acceleration of the particle, v = final velocity of the particle, u = Initial velocity of the particle, t = time.
From the question,
Given: u = 0 m/s (From rest), v = 15 m/s, t = 10 seconds
Substitute these values into equation 1
a = (15-0)/10
a = 15/10
a = 1.5 m/s²

Astronomers have measured that there is more helium in the universe than can be explained by the fusion in stars over the last 13 billion years. How do they think the extra helium got into the universe
Answer:
From big bang and stars.
Explanation:
The extra helium got into the universe through big bang and fusion reaction that occur in stars. Our universe formed about 13.7 billion years ago with big explosion, this event is known as big bang. The fusion of hydrogen nuclei in the stars produces helium and energy so we can say that most of the extra helium got into the universe through fusion reaction that occur in the stars continuously.
