Answer:

Series circuit

Explanation:

By definition series circuit is a closed circuit in which the flow of electric current follows only one path.

In a simple electrical circuit (which is a series circuit) where electric cell is the source of power, each component is connected in such a way that there is only one pathway current flows from the positive terminal(+) round to the negative terminal(-) via the external circuit.

Current having only one pathway to flow means that when one of the components is removed, there will be no current flow.

An object has a -8 C charge. The object breaks into two pieces. One piece has a charge of -2 C. What is the exact charge (in C)
Varvara68 [4.7K]

As we know the property of charge that charge is always conserved

so we can say

Q = q_1 + q_2

here we know that total charge is

Q = -8 C

and we also know that

q_1 = -2C

from above equation we can say

-8 = -2 + q_2

q_2 = -8 +2 = -6 C

so the other charge will be -6 C

Hey, guys I kinda need help with this question, 1. The number of atoms of each element are not equal on both sides of the equati
Xelga [282]

Answer:

The same number of atoms of each element must appear on both sides of a chemical equation. However, simply writing down the chemical formulas of reactants and products does not always result in equal numbers of atoms. You have to balance the equation to make the number of atoms equal on each side of an equation.

Physics, calculating net force. Please work it out for me
Margarita [4]

Answer:

F = 2985.125 N

Explanation:

Given that,

The radius of curvature of the roller coaster, r = 8 m

Speed of Micheal, v = 17 m/s

Mass of body, m = 65 kg  We need to find the net force acting on Micheal. Net force act the bottom of the circle is given by :

F=\dfrac{mv^2}{r}+mg\\\\F=m(\dfrac{v^2}{r}+g)\\\\=65(\dfrac{17^2}{8}+9.8)\\\\=2985.125\ N

So, the net force is 2985.125 N.

A gyroscope flywheel of radius 3.21 cm is accelerated from rest at 13.2 rad/s2 until its angular speed is 2450 rev/min.
SIZIF [17.4K]

Answer:

Part a)

a_t = 0.423 m/s^2

Part b)

a_c = 2113 m/s^2

Part c)

d = 80 m

Explanation:

Part a)

as we know that angular acceleration of the wheel is given as

\alpha = 13.2 rad/s^2

now the radius of the wheel is given as

R = 3.21 cm

so the tangential acceleration is given as

a_t = R\alpha

a_t = (0.0321)(13.2)

a_t = 0.423 m/s^2

Part b)

frequency of the wheel at maximum speed is given as

f = 2450 rev/min

f = \frac{2450}{60} = 40.8 rev/s

now we know that

\omega = 2\pi f = 2\pi(40.8) = 256.56 rad/s

now radial acceleration is given as

a_c = \omega^2 r

a_c = (256.56)^2(0.0321) = 2113 m/s^2

Part c)

total angular displacement of the point on rim is given as

\Delta \theta = \omega_0 t + \frac{1}{2}\alpha t^2

here we know that

\omega = \omega_0 + \alpha t

256.56 = 0 + 13.2 t

t = 19.4 s

now angular displacement will be

\Delta \theta = 0 + \frac{1}{2}(13.2)(19.4)^2

\Delta \theta = 2493.3 rad

now the distance moved by the point on the rim is given as

d = R\theta

d = (0.0321)(2493.3)

d = 80 m
