You have managed to get a vacation on the Moon where the gravitational field strength is 1.6 N/kg. Gleefully, you kick a ball of

mass 1.25 kg with an initial velocity of < 12, 12, 0> m/s. There is a goal post you can use as an origin marker where you kicked the ball. What is the initial momentum of the ball?

The initial momentum of the ball is 15 Kgms-1.

<h3>What is momentum?</h3>

In Physics, the term momentum is the product of mass and velocity. Momentum is a vector quantity. This implies that momentum possess both magnitude and direction.

Hence, we often write; p = mv

Where:

p = momentum

m = mass

v = velocity

The initial momentum therefore is;

p = 1.25 kg × 12 m/s = 15 Kgms-1

The elementary particle called a muon is unstable and decays in about 2.20μs2.20μs , as observed in its rest frame, into an elec
vredina [299]

Answer:

5.865 μs

Explanation:

t₀ = Time taken to decay a muon = 2.20 μs

c = Speed of Light in vacuum = 3×10⁸ m/s

v = Velocity of muon = 0.927 c

t = Lifetime observed

Time dilation

t=\frac{t_0}{\sqrt{1-\frac{v^2}{c^2}}}\\\Rightarrow t=\frac{2.2\times 10^{-6}}{\sqrt{1-\frac{(0.927c)^2}{c^2}}}\\\Rightarrow t=\frac{2.2\times 10^{-6}}{\sqrt{1-0.927^2}}\\\Rightarrow t=\frac{2.2\times 10^{-6}}{\sqrt{0.140671}}\\\Rightarrow t=\frac{2.2\times 10^{-6}}{0.3750}\\\Rightarrow t=5.865\times 10^{-6}\ seconds

∴Lifetime observed for muons approaching at 0.927 the speed of light is 5.865 μs

Jaipal measures a circuit at 1.2 A and 24 . Using Ohm’s law, what can he calculate for the circuit? current (C) current (I) volt
jenyasd209 [6]

Answer: voltage (V)

Explanation:

Hi, in the answer the letter A (1.2 A) stands for Ampere, and the symbol next to the number 24 must be Ω 8 (Ohms)

So, applying Ohm's law:

Voltage (V) =current (I) x resistance (R)

V = I x R

Replacing with the values given;

V = 1.2 A x 24Ω

In conclusion, we can calculate the value of Voltage for the circuit.

Feel free to ask for more if needed or if you did not understand something.

The force that one surface exerts on another when the two rub against each other is called
Alex777 [14]
1. Friction (Example: when you rub your hands together and you start to feel heat.)

2. Attract each other. (Example: Every object has a gravitational pull of some sort. The larger the object, the stronger the gravitational pull. This is why the sun is able to keep all eight planets in orbit around it.)

3. Hope this helped :)
