Which pendulum will.mobe faster​

Engineering
1 answer:
Amiraneli [1.4K]3 years ago
5 0

Explanation:

The period T (i.e. time to make one complete swing)

of a pendulum of length L is

T = 2 pi sqrt(L/g)

where g=acceleration due to gravity.

Note that the period is independent (to first order) of mass.

This means that the shorter the string, the shorter is the time (i.e. faster) it takes to make a complete swring.

Since the 5 kg mass is attached to a shorter swing, it will "move" faster, or the period T is shorter.

What is the net force acting on a car cruising at a constant velocity of 70 km/h (a) on a level road and (b) on an uphill road?
ElenaW [278]

Answer:

a) zero b) zero

Explanation:

Newton's first law tells us that a body remains at rest or in uniform rectilinear motion, if a net force is not applied on it, that is, if there are no applied forces or If the sum of forces acting is zero. In this case there is a body that moves with uniform rectilinear motion which implies that there is no net force.

Reptile [31]

Answer:

Timing Diagrams 15 pts. A 10 MHz clock that generates a 0 to 5V pulse train with a 30% duty cycle is connected to input X of a two input OR gate that has a 20nS propagation delay. The clock also goes to an inverter with a 10 ns propagation delay. The output of the inverter goes to the Y input of the OR gate. a) Draw the circuit. 2 pts. b) Plot the output of the clock for two cycles. Show times and voltages. 5 pts. c) On the same page as part (b) plot the output of the inverter. Show times and voltages. 3 pts. d) On the same page as parts (b & c) plot the output of the OR gate. Show times and voltages. 5 pts.

You are designing a system for a real-time application in which specific deadlines must be met. Finishing the computation faster
makvit [3.9K]

Answer / Explanation:

To proper understand the answers that is given to the question, we need to understand some basic terms that has been used in the question.

Energy: This can be refereed to as the quantitative property that is transferred to an object for the purpose of the object working or to heat up the object. It can also be referred to as conserved quantity that is energy can be converted from one form or state to another but cannot destroyed.

Power:  This can be defined as the rate of doing work or transferring heat per unit time from one state to another. The SI Units of power is watt which is equal to one joule per second.

Hence, the formula that links energy and power is:

Energy = Power x Time

Now. referring back to the question (a) asking how much energy do we save if we execute at the current speed and turn off the system when the computation is complete: The answer is  = 50%. That is 50% of the energy is saved.

(b) If we recall the formula for calculating energy,

we have:

Energy = 1 /2 Load x V²

Changing the frequency does not affect the energy.However, it affects the power.

So therefore, the new energy is 1 / 2 Load x ( 1/2 V)² ,

reducing it to about 1 /4 of the old energy.
