Increasing the mass attached to a spring will decrease the angular frequency of its vibrations. True or False

Physics
1 answer:
Scrat [10]3 years ago
4 0

Answer:

decreases

Explanation:

The angular frequency of the mass is given by

\omega =\sqrt{\frac{k}{m}}

where, k is the spring constant and m be the mass of the body which is doing oscillations.

if the mass of the body increases, so the value of angular frequency decreases, as the angular frequency is inversely proportional to the square root of the mass of the body.

Which type of rock would form from a lava following a volcanic eruption
melisa1 [442]

When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called extrusive igneous rocks. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian , and volcanic ash and dust.

Find the electric force acting on an alpha particle in a horizontal electric field of 600N/C
Sergeeva-Olga [200]
Since an alpha particle has 2 protons and no negative particles (electrons) to balance the net charge, its charge is
Q=2(1.6e-19)=3.2e-19C.
The force on a charged particle is F=QE so
(3.2e-19C)(600N/C)=1.92e-16N

A 60 W light bulb has a resistance of 880 Ω
Andreas93 [3]

<h2>\bf{ \underline{Given:- }}</h2>

\sf{• \:  Power \:  (P) = 60 \:  w}

\sf{•  \: Resistance \:  (R) = 880  \: Ω}

\sf• \:  The  \: Current \:  (I).

\\

\huge\bf{ \underline{ Solution :- }}

\sf We  \: know  \: that,

\bf \red {\bigstar{ \: P = I^{2} R}}

\rightarrow \sf 60 = I^{2}  \times 880

\rightarrow \sf  \frac{60}{880} = I^{2}

\rightarrow \sf  I^{2}   = 0.0681

A rock is thrown with a force of 500 N and an acceleration is 75 m/s^2. What is its mass?
artcher [175]

Answer:

We conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.

Hence, option D is correct.

Explanation:

Given

  • Force F = 500 N
  • Acceleration a = 75 m/s²

To determine

Mass m = ?

Important Tip:

  • The mass of a rock can be found using the formula F = ma

Using the formula

F = ma

where

  • F is the force (N)
  • m is the mass (kg)
  • a is the acceleration (m/s²)

now substituting F = 500, and a = 75 m/s² in the formula

F = ma

500 = m(75)

switch sides

m\left(75\right)=500

Divide both sides by 75

\frac{m\cdot \:75}{75}=\frac{500}{75}

simplify

m=\frac{20}{3}

m=6.7 kg

Therefore, we conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.

Hence, option D is correct.
