g 23.) [1 point] Which statement about images (formed by spherical mirrors and thin lenses) is true? Group of answer choices All

of the other statements listed are false. Thin lenses always produce real images because they transmit light. A virtual image cannot be seen by the human eye. Spherical mirrors always produce real images because they reflect light. A real image cannot be formed on a screen.

a toy dart gun has a spring with k=128 N/m. a kid pulls back on the spring with a 8.22 N force. how far does it stretch?(unit=m)
german

Answer:

0.064 m

Explanation:

When a spring is stretched/compressed, the force exerted in the spring is related to the elongation of the spring by the equation:

F=kx

where:

F is the force applied

k is the spring constant

x is the stretching/compression of the spring

In this problem, we have:

F=8.22 N is the force applied by the kid on the spring

k = 128 N/m is the spring constant

Solving for x, we find how far the spring stretches:

x=\frac{F}{k}=\frac{8.22}{128}=0.064 m

A mass attached to a spring is displaced from its equilibrium position by 5cm and released. The system then oscillates in simple
jok3333 [9.3K]

Answer:

C) 1 s

Explanation:

The period of a mass-spring system is given by the formula:

T=2\pi \sqrt{\frac{m}{k}}

where

m is the mass hanging on the spring

k is the spring constant

As we can see from the equation above, the period of the system does NOT depend on the initial amplitude of the oscillation. Therefore, even if the initial amplitude is changed from 5 cm to 10 cm, the period of the system will remain the same, 1 s.

An ant climbs at a steady speed up the side of its
lianna [129]

The weight of the ant is the force that acts on the anthill in the <u>downward direction</u> and at angle of 30° rom the vertical.

<u>Given the following data:</u>

  • Angle of inclination = 30.0°.

<h3>What is a free-body diagram?</h3>

In Science, a free-body diagram can be defined as a graphical illustration which is typically used to visualize moments, tension, and applied forces that are acting on an isolated or rigid body (object) while using arrows pointing in the direction of these forces.

In this scenario, the weight of the ant is the force that acts on the anthill in the <u>downward direction</u> and at angle of 30° rom the vertical.

Draw a picture of an atom.include protons,neutrons, and electrons.
gogolik [260]
Hey, unfortunately it’s impossible for me to draw one for you here, but you should be able to draw it yourself pretty easily!

Answer:


An atom is built with a combination of three distinct particles: electrons, protons, and neutrons. Each atom has a center nucleus, where the protons and neutrons are densely packed together. Surrounding the nucleus are a group of orbiting electrons. And here is a picture that may assist your further :

Hope this helps
