30 m/s
ker
24 m/s2
5 m/s
Answer:
5 m/s2
Explanation:
Using the equation velocity = initial velocity + (acceleration x time)
30 m/s = 0 + acceleration x 6 s
30 m/s = 6 s x acceleration
30 m/s / 6s = acceleration
acceleration = 5 m/s2

What is the power rating of an LED light bulb if 0.50 A flow through it when connected to an 18 V battery?
Remember to identify all data (givens and unknowns), list equations used, show all your work, and include units and the proper number of
significant digits to receive full credit
So, the power rating of that LED light bulb is 9 Watt.
IntroductionHi ! I will answer your question. This material is about electricity where You are instructed to calculate the rated power of a lamp. Always remember, the power required by the lamp must also be at least the same as the power from the mains so that the light is not too dim or the lamp does not explode.
Formulas UsedIn this question, the formula used is the formula for calculating power, which is the product of the voltage and current flowing. It can be seen mathematically as below:
[tex] \boxed{\sf{\bold{P = V \times I}}} [/tex] Or
[tex] \boxed{\sf{\bold{P = \frac{V^2}{R}}}} [/tex]
With the following condition :
P = power that needed (Watt or W)V = voltage that used (Volt or V)I = current that flowed (Ampere or A)R = resistance in electric tools (Ohm or [tex] \sf{\varOmega} [/tex])Problem SolvingWe know that :
V = voltage that used = 18 VI = current that flowed = 0.50 AWhat was asked :
P = power that needed = ... WStep by step :
[tex] \sf{P = V \times I} [/tex]
[tex] \sf{P = 18 \times 0.5} [/tex]
[tex] \boxed{\sf{P = 9 \: Watt}} [/tex]
Conclusion :So, the power rating of that LED light bulb is 9 Watt.

A variable resistor is set to a value of 5 ohms, and a current-voltage (I-V) graph (with I on the y-axis and V on the x-axis) is plotted for it. Its resistance is then doubled to 10 ohms. What effect will this have on its I-V graph?
When the resistance is doubled, the current reduces by half.
Ohms lawOhms law states that the voltage applied to a circuit is directly proportional to the current flowing in the circuit.

A box of spherical jawbreaker candies is 23 g and its volume is 32.3 cm3. If the average mass of a single jawbreaker is 0.94 g, what is the radius of a single jawbreaker
The radius of each jawbreaker is approximately 0.68 cm.
Volume of a sphere;v = 4 /3 πr³where
r = radius
Therefore,
23 g = 32.3 cm³
0.94 g = ?
cross multiply
volume of a single jawbreaker = 32.3 × 0.94 / 23 = 30.362 / 23 = 1.32 cm³
Therefore,
volume of each jawbreaker = 4 /3 πr³
1.32 = 4 / 3 × 3.14 × r³
r³ = 1.32 /4.18666666667
r³ = 0.31533683707
r = ∛0.31533683707
r = 0.680651651 = 0.68
Therefore, the radius of each jawbreaker is approximately 0.68 cm.

what is the valency of Sulphur!!
Explanation:
The sulphur atom has 6 electrons in the outermost shell, and its valency could be 6. But it is easier for sulphur to gain two electrons instead of losing six electrons. Hence, its valency is determined by subtracting six electrons from the octet and this gives a valency of two for sulphur.
A hiker travels 5.0 km north and then 2.5 km west What is the resultant displacement vector?
Answer: The resultant displacement vector is 5.6km
The resultant displacement vector of the hiker is equal to 5.6 km.
What is displacement?The distance can be described as the total length traveled by an object and is a scalar quantity with only magnitude. The distance should be always positive.
The displacement of an object can be described as the shortest length between two points. The displacement can be considered as a vector quantity with direction & magnitude. The displacement can be +ve, -ve, or zero and can be changed with time.
Given, a hiker moves 5.0 km along AB in the North and then 2.5 km west along BC.
The length (AC) is the resultant displacement that can be calculated by using Pythagoras' theorem:
AC² = AB² + BC²
AC² = (5.0)² + (2.5)²
AC² = 25 + 6.25
AC = 5.59 km ≈ 5.6 km
Therefore, the displacement of the hiker is 5.6 Km.

A locomotive is pulling 9 freight cars, each of which is loaded with the same weight. The mass of each loaded car is 37,000 kg, and we can neglect friction on these 9 cars. If the train is accelerating forward at 0.81 m/s^2 on a level track, what is the tension in the coupling between the second and third cars?
The tension in the coupling between the second and third cars is 269,730 N.
Tension in the coupling between the carsSince the weight of each car is the same, the applied force on each will be the same and the tension on the coupling between the cars will be the same.
T = F = ma
T = 9(37,000 x 0.81)
T = 269,730 N
Thus, the tension in the coupling between the second and third cars is 269,730 N.

students release a ball at the top of the inclined plane and measure the time for the ball to reach the bottom of the
ramp. The students perform three trials. The students then cover the board with a cloth and follow the same
procedure as before. The data are graphed below.
Part A
Describe two forces acting on the ball during the investigation.
Part B
Explain why the ball takes more time to roll down the ramp with a cloth surface.
Part C
Explain why the students repeated the investigation three times.
Part D
Explain how the ball's energy changes as the ball moves down the ramp.
Friction is the force that opposes motion.
What is friction?The term friction refers to the force that hinders the movement of a surface over another. The frictional force depends on the nature of the surfaces in contact.
1) The two forces acting on the ball during the frictional force are the forward force and the frictional force.
2) The ball takes more time to roll down the incline in the presence of the cloth because of the increase in friction of the surface.
3) The students repeated the investigation there times in order to ensure accuracy of the results.
