Answer:

frequency=1/time period

99HZ*time period=1

time period=1/99HZ

=0.01 second

Explanation:

Answer:

let Tension in the left chain is F

here, Fnet = 0

⇒F - 500N + 250 N - 125 N = 0

⇒F - 375 N = 0

⇒F = 375 N

let r from the left end of the board is the person sitting.

now torque at left end, τ = 0.

⇒375 × (0) - 500N × (r) + 250N × (4m) - 125 N × (2m) = 0

⇒0 - 500r + 1000 - 250 = 0

⇒750 = 500r

⇒r = 750/500 = 1.5 m

Answer: [tex]\alpha=4.798\ rad/s^2\quad [\text{deceleration}][/tex]

Explanation:

Given

Initial revolution of flywheel [tex]N_1=600\ rpm[/tex]

(Initial angular velocity [tex]\omega_i=\dfrac{2\pi N_1}{60}[/tex])

Final revolution of flywheel [tex]N_2=600\ rpm[/tex]

(Final angular velocity [tex]\omega_f=\dfrac{2\pi N_1}{60}[/tex])

Revolution turned [tex]34[/tex]

So, angle turned is [tex]\theta =2\pi \times 34\\[/tex]

Using equation of angular motion i.e. [tex]\omega_f^2-\omega_i^2=2\cdot \alpha \cdot \theta[/tex]

[tex]\Rightarrow \left(\dfrac{2\pi \times 416}{60}\right)^2-\left(\dfrac{2\pi \times 416}{60}\right)^2=2\alpha \times (68\pi )\\\\\Rightarrow \alpha=\dfrac{1898.344-3948.86}{427.312}\\\\\Rightarrow \alpha =-4.798\ rad/s^2\\\Rightarrow \alpha =4.798\ rad/s^2\quad [\text{deceleration}][/tex]

Answer: 4.5 billion years

Explanation:

Some of the water molecules in your drinking glass were created more than 4.5 billion years ago, according to new research.

That makes them older than the Earth, older than the solar system — even older than the sun itself.

Answer:

Basically, the main risk is cardiac arrest, caused by the electric current interfering with the normal operation of the heart muscle. Other possible damages are burns due to the electric energy vaporizing the water inside the cells, and nerve damage caused by excessive current through the nerves.

Answer:

a. V = 100 voltios

b. Para 120 V → [tex]R_{2} = 4 \Omega[/tex]

c. Para 110 V → [tex]R_{2} = 2 \Omega[/tex]

Explanation:

a. La tensión se puede calcular mediante la ley de Ohm:

[tex] V = IR [/tex]

V: es el voltaje o tensión =?

I: es la corriente = 5 A

R: es la resistencia = 20 Ω

Entonces, la tensión es:

[tex]V = IR = 5 A*20 \Omega = 100 V[/tex]

b. La resistencia adicional es la siguiente:

[tex] R_{2} + R_{1} = \frac{V}{I} [/tex]

[tex]R_{2} = \frac{V}{I} - R_{1} = \frac{120 V}{5 A} - 20 \Omega = 4 \Omega[/tex]

c. La resistencia adicional para operar a 110 voltios es:

[tex]R_{2} = \frac{V}{I} - R_{1} = \frac{110 V}{5 A} - 20 \Omega = 2 \Omega[/tex]

Answer:

v = 3.65 m / s

Explanation:

In this exercise we use the conservation of mechanical energy

starting point. Point A compressed spring

          Em₀ = 100 J

final point. Point B uncompressed spring

         Em_f = K = ½ m v²

energy is conserved

         Em₀ = Em₀_f

         100 = ½ m v²

         v = [tex]\sqrt{ \frac{2 \ 100 }{m} }[/tex]

         v = [tex]\sqrt {200/15}[/tex]

         v = 3.65 m / s

Answer:

A volcanic "hotspot" is an area in the mantle from which heat rises as a thermal plume from deep in the Earth. High heat and lower pressure at the base of the lithosphere (tectonic plate) facilitates melting of the rock. This melt, called magma, rises through cracks and erupts to form volcanoes.

Answer:

The weight of the water above a diver exerts pressure on their body. The deeper a diver descends, the more water they have above them, and the more pressure it exerts on their body

Answer:

t = 1.22 s

Explanation:

Given that,

The initial upward velocity component of a football = 12 m/s

The horizontal velocity component is 20 m/s

We need to find the time required for the football to reach the highest point of the trajectory. Let the time is t.

Using first equation of motion to solve it such that,

[tex]v=u+at[/tex]

u is initial velocity

v is final velocity

a = -g

so,

[tex]t=\dfrac{u}{g}\\\\t=\dfrac{12}{9.8}\\\\t=1.22\ s[/tex]

So, the required time taken by the football to reach the highest point is 1.22 seconds.

Answer:

325.76 revolutions

Explanation:

The tire radius is diameter/2: 42/2 = 21

And now we can discover the lenght of the tire circumference. The lenght of a circumference is given by 2×radius×π, and let's consider π=3.14, and let's use the radius in meter (21 cm = 0.21 m):

2•0.21•3.14 = 1.32 m of lenght

Now, you divide the distance the car moved by the lenght of the tire circumference and you will find how many revolutions the tire makes:

420/1.32 = 325.76
