Dependent Variable:
Control Group:
Constants (controlled conditions):

Materials: Just put what it contains.
Procedure: Now, for this just put what you need to do.
Results and Analysis: Then what you get after you do it.
Observations: What you have seen while you been doing this.
Data: just the things you know bout this.
Graph of Results: What it ends up like having.
Analysis Questions: Just questions about the chemicals
Conclusion: Just the ending a couple of sentences about what you've learned the chemicals etc...

Hope this help!

Static charges can be applied to neutral objects by friction, induction or conduction. What do all of these methods utilize to c
kvv77 [185]

Answer:

B) electrons

Explanation:

When charge is transferred by friction, induction or conduction, the charge carriers are the electrons.

In fact, protons and neutrons are found within the nucleus of the atoms, so they are tightly bound and they cannot be easily gained/given off. On the contrary, electrons are found in the electron clouds around the nucleus, so atoms can more easily gain/lose electrons, which become free and can be passed by an object to another.

The three methods of charging are:

- Friction: by rubbing two objects together, electrons may be transferred from one to another

- Induction: by moving a charged object closer to a neutral object, opposite charges in the neutral object migrate towards the opposite ends of the object, and if the object is connected to the ground, the charges of one polarity leave the object, leaving the object charged

- Conduction: by putting a charged object in contact with a neutral object, electrons can be transferred from the charged object to the neutral one

3. The circuit below shows two outdoor lights, run by a battery. Four amps of
miv72 [106K]

Answer:

The answer to your question is given below.

Explanation:

From the diagram given in the question, we can see that the bulbs are in parallel connection. This implies that different current will go through the bulb but the same voltage. But the resistance of each bulb is the same, therefore the same current current will go through them.

This can further be understood if we determine the current flowing through each bulb. This is illustrated below:

Voltage (V) = 30V

Resistant 1 (R1) = 15Ω

Current 1 (I1) =..?

V = I1R1

30 = I1 x 15

Divide both side by 15

I1 = 30/15

I1 = 2A.

Voltage (V) = 30V

Resistant 2 (R2) = 15Ω

Current 2 (I2) =..?

V = I2R2

30 = I2 x 15

Divide both side by 15

I2 = 30/15

I2 = 2A.

The overall current(I) in the circuit:

I = I1 + I2

I = 2 + 2 = 4A.

From the illustrations above, we can see that the same current will flow through each bulb as the will current split into two equal parts

A knife thrower throws a knife toward a 300 g target that is sliding in her direction at a speed of 2.30 m/s on a horizontal fri
zhannawk [14.2K]

Answer:

The speed of the knife after passing through the target is 9.33 m/s.

Explanation:

We can find the speed of the knife after the impact by conservation of linear momentum:

p_{i} = p_{f}

m_{k}v_{i_{k}} + m_{t}v_{i_{t}} = m_{k}v_{f_{k}} + m_{t}v_{f_{t}}

Where:

m_{k}: is the mass of the knife = 22.5 g = 0.0225 kg

m_{t}: is the mass of the target = 300 g = 0.300 kg

v_{i_{k}}: is the initial speed of the knife = 40.0 m/s

v_{i_{t}}: is the initial speed of the target = 2.30 m/s

v_{f_{k}}: is the final speed of the knife =?

v_{f_{t}}: is the final speed of the target = 0 (it is stopped)

Taking as a positive direction the direction of the knife movement, we have:

m_{k}v_{i_{k}} - m_{t}v_{i_{t}} = m_{k}v_{f_{k}}  

v_{f_{k}} = \frac{m_{k}v_{i_{k}} - m_{t}v_{i_{t}}}{m_{k}} = \frac{0.0225 kg*40.0 m/s - 0.300 kg*2.30 m/s}{0.0225 kg} = 9.33 m/s

Therefore, the speed of the knife after passing through the target is 9.33 m/s.

I hope it helps you!
