Which type of energy is stored in a battery?
O A. Nuclear energy
O B. Electrical energy
O C. Electromagnetic energy
O D. Chemical energy
Answer:
Chemical energy is in a battery
The type of energy is stored in a battery is Chemical energy (option d)
Batteries store chemical energy. When a battery is charged, a chemical reaction occurs inside it, converting the reactants into different products. This process stores energy in the form of chemical bonds within the battery's components.
When you use the battery to power a device, the reverse chemical reaction takes place, releasing the stored energy as electrical energy. This flow of electrons creates an electric current that powers the device connected to the battery.
The capacity of a battery to store and release energy depends on the type and quantity of chemicals used in its construction. Different types of batteries, such as alkaline, lithium-ion, or lead-acid batteries, have varying chemical compositions, affecting their energy storage capabilities and overall performance.
So, the correct option is (d).

2. The Himalayas in central Asia are the tallest mountains in the world. But fossils of seashells can be found high in these mountains, far from any ocean.
How do you think they got there?
Answer:
The sea level could have been much higher in the past.
Explanation:
The tectonic plates shifted and the mountain rose from there.
They are trapped throughout the rock whereas the seashells have been on the floor of a modest seafloor.
These same containers dropped down on the base of the silt level or sheet, as well as those layering finally became rock.Few more million generations previously, the Indian civilization or the subcontinent crashed well with the continents of Asia, making the Himalayan mountains rock which thus previously were such a sea level.
Thus the above response is appropriate.

A swimmer sets off headed west at 0.40 m/s directly towards the opposite shore of a swift river. The swimmer makes it to the opposite shore 30 meters downstream of their expected position. If the river is 7.5 meters wide, what is the velocity of the water relative to the shore?
Answer:
Explanation:
River is 7.5 m wide . Time taken by it cover this displacement
= displacement / velocity
= 7.5 / 0.4
= 18.75 s
During this period , swimmer will have a displacement of 30 m due to velocity of river water .
Displacement of 30 m downstream will be due to flow of river .
velocity of water flow = displacement / time
= 30 / 18.75
= 1.6 m /s
Which of these BEST explains how Earth's surface features are formed by moving tectonic plates? *
5 points
Earth's gravity acts as an opposing force, causing the crust to push upward, break into individual plates, and move along the surface.
The minerals in lithospheric plates are attracted to Earth's magnetic poles, which causes them to move along the surface.
The spinning of Earth's outer core causes the lithosphere to break into individual plates and collide with each other.
Earth's crust is separated into individual plates that float on top of molten material, convection currents in the mantle cause them to slowly move.
Answer: The spinning of Earth's outer core causes the lithosphere to break into individual plates and collide with each other.
Earth's surface forms because of this reason:
The spinning of Earth's outer core causes the lithosphere to break into individual plates and collide with each other.
A 4kg block and a 2kg block can move on horizontal frictionless surface. The blocks are accelerated by a +12-N force that pushes the large block against the smaller one.'
a) Determine the force that the 2kg block exerts on the 4kg block
b) Determine the force that the 4kg block exerts on the 2kg block.
Answer:
a) -4 N
b) +4 N
Explanation:
Draw a free body diagram for each block.
For the large block, there are 2 forces: 12 N pushing to the right, and F pushing to the left.
For the small block, there is 1 force, F pushing to the right.
There are also weight and normal forces in the vertical direction, but we can ignore those.
Sum of forces on the large block in the x direction:
∑F = ma
12 − F = 4a
Sum of forces on the small block in the x direction:
∑F = ma
F = 2a
2F = 4a
Substitute:
12 − F = 2F
12 = 3F
F = 4
The small block pushes on the large block 4 N to the left (-4 N).
The large block pushes on the small block 4 N to the right (+4 N).
A truck traveling at a velocity of 33m/s comes to a halt by decelerating at 11m/s^2. How far does the truck travel in the process of stopping. identify known variables such as V, V0, a, t, and delta x.
Answer:
The truck was moving 16.5 m/s during the time it took to stop, which was 3 seconds.
Initial velocity = 33 m/sFinal velocity = 0 m/sAverage velocity = (33 + 0) / 2 m/s = 16.5 m/sExplanation:
First, how long does it take the truck to come to a complete stop?( 33 m/s ) / ( 11 m / s^2 ) = 3 secondsThen we can look at the average velocity between when the truck started decelerating and when it came to a complete stop. Because the deceleration is constant (always 11m/s^2) we can use this trick.The time taken to stop the truck is 3 seconds. The final velocity is zero. Then, the distance travelled by the truck is 49.5 m.
What is acceleration ?Acceleration is a physical quantity that, measures the rate of change in velocity. It is a vector quantity thus having both magnitude and direction. It can be defines as the ratio of change in velocity to the change in time.
Given initial velocity = 13.5 m/s
final velocity is zero since the bicycle is stopping.
then Δt = Δv/a
Δt = 33 m/s/ 11 m/s² = 3 seconds.
Hence, the truck will take 3 s to complete stop.
The distance covered within this time can be determined using the equation as follows:
s = u t + 1/2 at²
where u is the initial velocity
The acceleration a = - 11 m/s² the minus sign is due to deceleration.
s = (33m/s × 3 s) + (-11 m/s² ×3 s ×3 s) = 49.5 m.
Therefore, the truck will travel up to 49.5 m before stopping.

how much faster will a car be going if it accelerates at 1 m/s/s for a total of 60 seconds.
Answer:
Vf = 60 [m/s]
Explanation:
To solve this problem we must use the following equation of kinematics.
[tex]v_{f}= v_{i}+(a*t)[/tex]
where:
Vf = final velocity [m/s]
Vi = initial velocity = 0
a = acceleration = 1 [m/s^2]
t = time = 60 [m]
Now replacing:
Vf = 0 + (1*60)
Vf = 60 [m/s]
A baseball is hit into the air with a velocity of 27 m/s. How high does it go?
Answer:
Explanation:
If a baseball is hit into the air with a velocity of 27 m/s, we want to determine the maximum height of the ball. Using the projecile formula;
Max height H = u²/2g
u is the initial velocity of the body = 27m/s
g is the acceleration due to gravity = 9.81m/s²
H = 27²/2(9.81)
H = 729/19.62
H = 37.16m
Hence the ball went 37.16m high
A car is initially moving at 10.5 m/s and accelerates uniformly to reach a speed of 21.7 m/s in 4.34 s. How far did the car move during this acceleration?
A. 69.9m
B. 6.99m
C. 69.6m/s
D. 6.99m/s
Answer:
A. 69.9m
Explanation:
Given parameters:
Initial velocity = 10.5m/s
Final velocity = 21.7m/s
Time = 4.34s
Unknown:
Distance traveled = ?
Solution:
Let us first find the acceleration of the car;
Acceleration = [tex]\frac{v - u}{t}[/tex]
v is final velocity
u is initial velocity
t is the time
Acceleration = [tex]\frac{21.7 - 10.5}{4.34}[/tex] = 2.58m/s²
Distance traveled;
V² = U² + 2aS
21.7² = 10.5² + 2 x 2.58 x S
360.64 = 2 x 2.58 x S
S = 69.9m
A car is traveling down the highway cruise control at 50m/s (this means its is traveling with a constant velocity NOT accelerating). If it does this for 5 minutes (300s), how far does it travel?
Given parameters:
Speed of car = 50m/s
Time of travel = 5minutes (300s)
Unknown;
Distance of travel = ?
To solve this problem, we need to understand how speed relates with distance and time.
Speed is a physical quantity. It is the distance traveled divided by time taken.
Speed = [tex]\frac{distance}{time}[/tex]
So,
Distance = speed x time
Input the parameters and solve for the distance;
Distance = 50m/s x 300s
Distance = 15000m
The distance covered during this time interval and speed is 15000m

A man weighing 490N on earth weighs 81.7N on the moon.His mass on the moon is kg
His mass is 50 kg . . . on the Moon, on the Earth, in the capsule rocketing between them, and on Halley's comet if he ever goes there.
Answer:
50kg
Explanation:
The mass of a man on the Earth and the moon is the same, so we only need to use the 490N weight on Earth.
The formula for mass is m=w/g. Plugging in the values, we can determine that m=490N/9.8m/s^2. (g is gravitational constant, which is approximately 9.8m/s^2 on Earth)
The reason that the unit in the answer is in kg is because one newton (N) is 1kg*m/s^2. The m/s^2 is cancelled out by the m/s^2 in the gravity constant, so it leaves kg.
m=50kg
