This being a perfect collision means no energy is lost during the collision. Because this question asks for speed and not velocity, the speed will be the same because the final energy is the same. The speed after the collision would therefore be 1.27 m/s.

A group of students collected the data shown below while attempting to measure the coefficient of static friction (of course, it

anzhelika [568]

Answer:

0.130

Explanation:

From the given data, the coefficient of static friction for each trial are:

1. 0.053

2. 0.081

3. 0.118

4. 0.149

5. 0.180

6. 0.198

The sum of the coefficient of static friction = 0.053 + 0.081 + 0.118 + 0.149 + 0.180 + 0.198

= 0.779

So that;

the average coefficient of static friction = $\frac{sum of coefficient of static friction}{number of trials}$

= $\frac{0.779}{6}$

= 0.12983

The average coefficient of static friction is 0.130

Three capacitors (4.7, 6.5, and 15.5 F) are connected in series across a 50.0-V battery. Find the voltage across the 4.7-F capac

satela [25.4K]

Answer: 50 V

Explanation:

Given

Three capacitors are connected in parallel across 50 V battery

When capacitor are connected in parallel, net capacitance is the sum of all the values

Net capacitance

$\Rightarrow C=4.7+6.5+15.5\\\Rightarrow C=26.7\ F$

Voltage in parallel circuit is same across each capacitor. Therefore, voltage across 4.7 F capacitor is 50 V

In what state must matter exist for fusion reactions to take place

steposvetlana [31]

Answer:

Plasma

Explanation:

For a fusion reaction to take place, there must be conditions in which the particles have extreme thermal kinetic energies, in this way the collisions that cause the nuclear fusion are generated. Therefore, it is necessary to reach very high temperatures, in which the state of matter will necessarily be plasma.
