Ilya [14]

Answer:

The frequency of vibration will be unchanged.

Explanation:

The frequency of oscillation of a simple pendulum is given by

f = \dfrac{1}{2 \pi}\sqrt{\dfrac{g}{L}}

where, g is the acceleration due to gravity and L is the length of the pendulum.

It can be seen from the formula that the frequency of the pendulum is independent of the mass.

Thus, the frequency of vibration will be same.

A 1200 kg car traveling east at 4.5 m/s crashes into the side of a 2100 kg truck that is not moving. During the collision, the v
Rasek [7]

Answer:

Explanation:

This is a simple Law of Momentum Conservation problem of the inelastic type. The equation for this is

[m_1v_1+m_2v_2]_b=[(m_1+m_2)v]_a  Filling in:

[1200(4.5)+2100(0)]=[(1200+2100)v] which simplifies to

5400 + 0 = 3300v

so v = 1.6 m/s to the east, choice B

How do you know when electric current is flowing in a lightbulb circuit?
daser333 [38]
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.

A 2 kg mass is free falling in the negative Y direction when a 10 N force is exerted in the minus X direction. What is the accel
lara31 [8.8K]

Answer:

The mass's acceleration is 5 m/s^2 in the minus X direction and 9,8 m/s^2 in the minus Y direction.

Explanation:

By applying the second Newton's law in the X and Y direction we found that in the minus X direction an external force of 10 N is exerted, while in the minus Y direction the gravity acceleration is acting:

X-direction balance force: -10 [N] = m.ax

Y-direction balance force: -m*9,8 \frac{m}{s^2} = m.ay

Where ax and ay are the components of the respective acceleration and m is the mass. By solving for each acceleration:

ax=(-10 [N]) / m

ay=-m*9,8\frac{m}{s^2} / m

Note that for the second equation above the mass is cancelled and, the Y direction acceleration is minus the gravity acceleration:

ay=-9,8\frac{m}{s^2}

For the x component aceleration we must replace the Newton unit:

N =\frac{kg.m}{s^2}

ax= -10 \frac{kg.m}{s^2} / (2 kg)

ax= - 5 \frac{m}{s^2}
