7. Reid runs away from Joharri after an intense political debate. His initial acceleration is

disa [49]

Answer:

0.6944 m/sec^2

Explanation:

The computation of the average acceleration is given below:

a = v - u ÷ t

where

a denotes average acceleration

v denotes final velocity

u denotes initial velocity

t denotes time

So, the average acceleration is

= (25 - 0) ÷ 10

= 0.6944 m/sec^2

A crate of eggs is located in the middle of the flatbed of a pickup truck as the truck negotiates a curve in the flat road. The

oksian1 [2.3K]

Answer:

v = 14.35 m/s

Explanation:

As we know that crate is placed on rough bed

so here when pickup will take a turn around a circle then in that case the friction force on the crate will provide the necessary centripetal force on the crate

So here we have

$\mu mg = \frac{mv^2}{R}$

here we have

$\mu g = \frac{v^2}{R}$

now we know that

$v = \sqrt{\mu Rg}$

here we have

$\mu = 0.600$

R = 35 m

g = 9.81 m/s/s

now plug in all values in above equation

$v = \sqrt{(0.600)(35)(9.81)}$

$v = 14.35 m/s$

What is the wavelength in nanometers of light when the energy is 1. 91 × 10^6 j for a mole of photons?.

JulijaS [17]

The wavelength in nanometers of light when the energy is 1. 91 × 10^6 j for a mole of photons is 62. 8 nm.

Wavelength is the distance among the same points (adjacent crests) within the adjoining cycles of a waveform signal propagated in space or along a cord. In wi-fi structures, this period is typically specified in meters (m), centimeters (cm), or millimeters (mm).

The wavelength is the distance between wave crests, and it is going to be the same for troughs. The frequency is the variety of vibrations that skip over a given spot in one 2nd, and it's far measured in cycles consistent with the second (Hz) (Hertz).

Frequency is the ratio of pace and wavelength in relation to speed. In comparison, wavelength refers to the ratio of pace and frequency. Audible sound waves are characterized by way of a frequency range of 20 to 20 kHz. In contrast, the variety of wavelengths of visible light is from four hundred to seven hundred nm.

calculation:-

*E=hc/λ

1.91 × 10^6 J = (6.62610⁻³⁴) (3.00*10⁸) / λ

λ= (6.62610⁻³⁴) (3.00*10⁸) / 1.91 × 10⁶ J

λ= 1.0410⁻³¹× 10⁻⁹ × 6.022*10²³

= 62. 8 nm
