An object's natural frequency depends partially on the material from which it is made.

true - material determines its strength, hardness, elasticity n other physical properties dat affect its natural frequency. other factors include the shape n size of the object.

Yes. Partly. Also on the size and shape of the object, and also on what material it's IN at the time ... like air, water, Helium, Jello, etc.

What property is primarily responsible for determining the type of electromagnetic energy and peak wavelength emitted by a star

Galina-37 [17]

Answer:B. Temperature

Explanation:The temperature of the star such as Sun is measured. Using this measurement, its peak wavelength and energy can be determined.For determination of wavelength, Wien's displacement law is used. This law states that, the sun like body emits all kinds of wavelengths and thus is nearly a black body.For black body, the peak wavelength emitted is inversely proportional to the temperature of the body. From the wavelength, energy can be calculated.Temperature is the property which is primarily responsible for determining the type of electromagnetic energy and peak wavelength emitted by star.

A cube, whose edges are aligned with the , and axes, has a side length . The field is immersed in an electric field aligned with

Ivenika [448]

Complete Question

Complete Question is attached below

Answer:

$q=1.558*10^{-9}c$

Explanation:

From the question we are told that:

Side length s=1.13m

Left field strength $E_l=784.75N/m$

Right field strength $E_r=776.38 N/m$

Front field strength $E_f=725.5 N/m$

Back field strength $E_b=749.54 N/m$

Top field strength $E_t=944.95 N/m$

Bottom field strength $E_{bo}=1082.58 N/m$

Generally, the equation for Charge flux is mathematically given by

$\phi=EAcos\theta$

Where

Theta for Right,Left,Front and Back are at an angle 90

$cos 90=0$

Therefore

$\phi =0$ with respect to Right,Left,Front and Back

Generally, the equation for Charge Flux is mathematically also given by

$\phi=\frac{q}{e_o}$

Where

$Area =L*B\\\\A=1.13*1.13\\\\A=1.2769m^2$

Therefore

$Q_{net}=E_{bo}Acos\theta_{bo} +E_tAcos\theta_t$

$Q_{net}=1082.85*1.2769*cos0=944.95*1.2769cos (180)$

$Q_{net}=176N/C m^2$

Giving

$q=\phi*e_0$

$q=176N/C m^2*1.558*10^{-12}c$

$q=1.558*10^{-9}c$

klasskru [66]

use the formula

v= u+ at

v is final velocity , u is initial velocity , a is acceleration and t is time

put the values

Why does the quantity of helium found in the universe support the big bang theory?

Nostrana [21]

The correct option is D.
The big bang theory is the scientific theory that explains how the universe came to exist. The theory explains how the universe expanded due to high temperature and density. Scientists believed that the first nuclei were formed few minutes after the bing bang occurred via a process called bing bang nucloesynthesis. During this process helium and hydrogen were formed and the amount of helium found correspond to the amount predicted by scientists.
