Answers

When the resistance is doubled, the current reduces by half.

Ohms law

Ohms law states that the voltage applied to a circuit is directly proportional to the current flowing in the circuit.

V = IR

V/R = I

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

Answers

So, the power rating of that LED light bulb is 9 Watt.

Introduction

Hi ! 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 Used

In 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 Solving

We know that :

V = voltage that used = 18 VI = current that flowed = 0.50 A

What was asked :

P = power that needed = ... W

Step 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.

Students place the end of a wooden board on some books so that the board can be used as an inclined plane. The
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.

Answers

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.

4) The energy of the ball changes from potential energy at the top of the ramp to kinetic energy as it rolls down the ramp.

A hiker travels 5.0 km north and then 2.5 km west What is the resultant displacement vector?​

Answers

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 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

Answers

The radius of each jawbreaker is approximately 0.68 cm.

Volume of a sphere;v = 4 /3 πr³

where

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.

If a box that weighs 4.00 N slides across a flat rough table for a distance of 2.00 m then how much work does the weight of the box
do on the box?
A) 88.0 J
B) 456 J
C) 270 J
D) 513 J
E)zero

Answers

Answer:

0

Explanation:

Here it's given that the weight of the box is 4N and it slides across a rough table for a distance of 2m . And we are interested in finding out the work done by the weight of the block. Firstly we know that , Work done is ,

[tex]\rm\longrightarrow \pink{ Work\ = \ F.s = |F||s|cos\theta} [/tex]

where

[tex]\theta[/tex] is the angle between displacement and force .

Therefore ,

[tex]\rm\longrightarrow Work = (4N)(2m)(cos\theta) [/tex]

Here the angle between the displacement and force is 90° , and value of cos90° is 0 , therefore,

[tex]\rm\longrightarrow Work = 8N-m (0)\\[/tex]

[tex]\rm\longrightarrow \underline{\boxed{\rm\blue{Work = 0 }}}[/tex]

The work done by the weight of the box is zero. The correct answer is zero. The correct option is (E).

Given:

Weight of the box = 4.00 N (acting downward)

Distance = 2.00 m

The angle between force and displacement, θ = 90°

Using the formula for work:

Work (W) = Force × Distance × cos(θ)

Since the angle θ is 90 degrees and cos(90 degrees) = 0.

The work done by the weight of the box is:

W = Force × Distance × cos(90)

W = 4.00 × 2.00 × 0

W = 0 J

Therefore, the work done by the weight of the box is zero. The correct option is (E).
