In an experiment involving pendulums, you want to see how changing the mass of the bob affects the period (amount of time) of a

pendulum swing. What would be your dependent variable?

Answer:

The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.

Since this object is traveling at terminal velocity, what must be the value of Fd? (HINT: how to the lengths of both arrows comp
Juli2301 [7.4K]

The magnitude of the air drag when the object is traveling at terminal velocity is C. 850 Newtons

Explanation:

There are only two forces acting on the object here:

- The force of gravity, of magnitude F_g = 850 N, acting downward

- The air drag, F_d, acting upward

Therefore, the equation of motion for the object is

F_g - F_d = ma

where m is the mass of the object and a its acceleration.

The object in this problem is traveling at terminal velocity: this means that the acceleration is zero, so

a = 0

Therefore the equation becomes

F_d = F_g

which means that the magnitude of the air resistance is equal to the magnitude of the force of gravity:

F_d = 850 N

Radioactive nuclei decay to become unstable. Is this true or false?
Damm [24]

The unstable nuclei undergo radioactive decay. The nucleus decay in form of emitting the radiations or changing into the different chemical element.

Thus, the nucleus decay takes place till the nuclei become stable.

Hence, given statement is false.

A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500 J. What is the mass of the soccer ball
Savatey [412]
A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500 J.The mass of the soccer ball is 0.4 kgs. This answer is derived from the formula K=1/2 MV^2.So velocity and kinetic energy are given from that mass of the ball is calculated.By substituting the values 500=1/2*M*50*50 which gives M=0.4 Kgs.<span>

Max is a network technician who just terminated the ends on a new copper cable used between two legacy switches. When he connect
Olegator [25]

Answer:

The cable used is a straight through cable.

Explanation:

The cable used here is a straight through cable, that is why it fails to establish the connection.

Cross-over cables are used to communicate over legacy switch. It is used to connect computing devices directly.

In a cross over cable, signal gets transmit from one end of the device to the other.

An ideal parallel plate capacitor with a cross-sectional area of 0.4 cm2 contains a dielectric with a dielectric constant of 4 a
Mrrafil [7]

Answer: 283.2\times 10^{-9}\ nC

Explanation:

Given

Cross-sectional area A=0.4\ cm^2

Dielectric constant k=4

Dielectric strength E=2\times 10^8\ V/m

Distance between capacitors d=5\ mm

Maximum charge that can be stored before dielectric breakdown is given by

\Rightarrow Q=CV\\\\\Rightarrow Q=\dfrac{k\epsilon_oA}{d}\cdot (Ed)\quad\quad [V=E\cdot d]\\\\\Rightarrow Q=k\epsilon_oAE\\\\\Rightarrow Q=4\times 8.85\times 10^{-12}\times 0.4\times 10^{-4}\times 2\times 10^8\\\\\Rightarrow Q=28.32\times 10^{-8}\\\\\Rightarrow Q=283.2\times 10^{-9}\ nC
