Muscular Endurance refers to the ability for a muscle to work against a resistance for an extended period of time

Endurance :-

Perseverance is connected with the capacity to perform work over a drawn out timeframe. Youngsters, for instance, can play effectively for hours. Endurance can be impacted by a singular muscle, a muscle bunch, or the complete body. Muscle perseverance mirrors the capacity to support rehashed muscle compression and is connected with muscle strength.

What is the resistance of an electric frying pan that draws 12 amperes of current when connected to 120 Volt circuit

Blizzard [7]

10 ohms

Explanation

the resistance of an electric circuit is given by:

$\begin{gathered} R=\frac{V}{I} \\ where\text{ R is the resitance} \\ Vi\text{s the voltage} \\ I\text{ is the current} \end{gathered}$

Step 1

a) let

$\begin{gathered} R=R \\ V=120\text{ volts} \\ I=12\text{ Amperes} \end{gathered}$

b) now, replace in the expression

$\begin{gathered} R=\frac{V}{I} \\ R=\frac{120\text{ volt}}{12\text{ Amp}} \\ R=10\text{ ohms} \end{gathered}$

therefore, the answer is

10 ohms

A 0.01 kg bullet is fired at a 0.5 kg block initially at rest. The bullet, moving with an initial speed of 400 m/s, emerges from

kondor19780726 [428]

Use the law of conservation of momentum to solve this problem. We have a system of two bodies (bullet and block). Initially, only the bullet has a non-zero momentum. After the collision, both have some momentum and we know the part for the bullet, so it is simple to isolate the part for the block. Call v_t0 the initial bullet speed, v_t1 new bullet speed, v_k speed of block. (similarly for masses):

$m_t\cdot v_{t0}=m_t\cdot v_{t1} + m_k\cdot v_k\implies\\v_k=\frac{m_t\cdot v_{t0}-m_t\cdot v_{t1}}{m_k}=\frac{0.01kg\cdot(400-300)m/s}{0.5kg}=2\frac{m}{s}$

The block will move with a speed of 2 m/s in the direction of the bullet.

Discuss why the article says the fact that we’re in our universe complicates our understanding of the expansion of the universe.

MArishka [77]

<span>Because of our perception of the universe from inside the universe, we are unable to see how and towards what the universe is expanding. Also, our understanding of it is further complicated because we are moving as part of the expansion, thus distorting our perception of it.</span>
