If it is a matter of which way you are going you could lean forward. It would help to put all the weight opposite of where you are falling.

g determine what frequency is required of a source powering a 100 uf capacitor a 500 ohm resistor and a s50 mH inductor in serie

polet [3.4K]

Answer: $71.16\ Hz$

Explanation:

Given

Capacitance $C=100\ \mu F$

Resistance $R=500\ \Omega$

Inductance $L=50\ mH$

In LCR circuit, current is maximum at resonance frequency i.e.

$X_L=X_C\ \text{and}\ \omega_o=\dfrac{1}{\sqrt{LC}}$

Insert the values

$\Rightarrow \omega_o=\dfrac{1}{\sqrt{50\times 10^{-3}\times 100\times 10^{-6}}}\\\\\Rightarrow \omega_o=\dfrac{1}{\sqrt{5}\times 10^{-3}}\\\\\Rightarrow \omega_o=0.447\times 10^{3}$

Also, frequency is given by

$\Rightarrow 2\pi f=\omega_o\\\\\Rightarrow f=\frac{\omega_o}{2\pi}$

$\Rightarrow f=\dfrac{1}{2\pi}\times 0.447\times 10^3\\\\\Rightarrow f=71.16\ Hz$

Answer:

When an object is immersed in water. it is pulled downwards due to gravitational pull of earth. Water exerts upward force on the object. This makes object rise up. This upward force is called buoyancy or upthrust.

Mammals must eliminate waste products that their bodies produce. Which organ helps mammals eliminate bodily waste?

Arada [10]

Answer:

Digestion helps mammals eliminate bodily waste.

Explanation:

Humans are considered mammals and we use digestion to eliminate bodily waste. Digestion has three main functions. First digestion of food, second absorption of nutrients, and third elimination of solid waste. There are two processes that take place Mechanical digestion and chemical digestion. Mechanical digestion is the chewing and breaking down of food into smaller molecules, whereas chemical digestion is the breakdown of the smaller molecules into simpler nutrients that the body can absorb and use.

A skater pushes off a wall and skates backward for a few meters before stopping.

Inessa05 [86]

Answer:

Explanation:

Newton's Third Law (Law of Action-Reaction) states:

Every action has an equal and opposite reaction and it occurs between two objects

In this scenario, the action would be the skater pushing off of the wall, therefore the reaction would be the wall pushing off of the skater since the two objects that are interacting are the wall and the skater.

a college student produces about 100 kcal of heat per hour on the average what is the rate of energy production and joules

Bond [772]

Given:

Amount of heat produced = 100 kcal per hour

Let's find the rate of energy production in joules.

We know that:

1 calorie = 4.184 Joules

1 kcal = 4.184 Joules

To find the rate of energy production in Joules, we have:

$\begin{gathered} Rate=100\ast4.184 \\ \\ \text{Rate}=418.4\text{ KJ/hour} \end{gathered}$

Therefore, the rate of energy production in joules is 418.4 kJ/h which is equivalent to 418400 Joules

ANSWER:

418.4 kJ/h
