The answer is option B "anaerobic." Weightlifting deals with stress to the muscles when lifting weights and due time the muscles will begin to adapt and get stronger. Other examples of anaerobic exercise are things like: weight training, sprinting, cycling, and jumping anything that has short exertion, and high-intensity movement is an anaerobic exercise.

Hope this helps!

A capacitor is connected to an ac generator that has a frequency of 3.4 kHz and produces a voltage of 2.0 V. The current in the

garik1379 [7]

Answer:

$V_G=3.302857143V$

Explanation:

Let´s find the capacitor impedance:

$V=IZ_C$

Using the data provided:

$Z_C=\frac{V}{I}=\frac{2}{0.035}=57.14285714$ Ω

Now let´s find the capacitance:

$Z_C=\frac{1}{j2\pi fC }$

$C=\frac{1}{j2\pi fZ_C} =\frac{1}{j2\pi (3400)(57.14285714)}= 0.8191798542$ μF

We can calculate the capacitor impedance for the second case:

$Z_C=\frac{1}{j2\pi fC}=\frac{1}{j2\pi (5000)(0.8191798542X10^{-6}) }=38.85714285$ Ω

Finally we can calculate the voltage of the second generator:

$V_G=IZ_C=(0.085)(38.85714285)=3.302857143V$

Using the results of Question 1 that would apply if the collision were inelastic, compute (using Excel in the yellow highlighted

ch4aika [34]

Answer:

The fractional kinetic energy will be lost if the collision is inelastic. In inelastic collision, the kinetic energy is converted into other forms of energy.

The lost energy became heat and sound energy.

Explanation:

During inelastic collision, the kinetic energy of a moving object does not conserve. It changes into another form of energy such as sound energy and heat energy etc.

For example, when a moving car hit another car or wall etc, the kinetic energy is converted into sound and heat energy. This type of collision is inelastic collision.

How much work was done to accelerate a 2.2 kg object from rest to 26m/s?

Makovka662 [10]

Answer:

Explanation:

work done = change in kinetic energy, assuming there are no energy losses.

work done = 1/2 × m × change in v^2

= 1/2 × 2.2 × ( 26^2 - 0^2)

= 1/2 × 2.2 × 676

= 743.6 joules

A ramp with a mechanical advantage of 8 lifts objects to a height of 1.5 meters how long is the ramp

AlekseyPX

Given data:

M.A. = 8 (No units),

Ramp height (h)= 1.5 m, lifted,

Determine how long is the ramp=?

General formula 

 Mechanical Advantage = (Ramp length) ÷ (Ramp height),

 M.A = l ÷ h 

 8 × 1.5 = l = 12 m long

length of the ramp l ramp = 12 m
