How much energy, in Joules, is needed to raise the temperature from 25.87°C to 33.16°C in a 2.66 kg block of each of the followi

RUDIKE [14]

Answer:

(a) Silver, H = 455.67 J

(b) Iron, H = 870.67 J

Explanation:

mass of block, m = 2.66 kg = 266 g

T1 = 25.87° C

T2 = 33.16° C

ΔT = T2 - T1 = 33.16 - 25.87 = 7.29° C

(a) Specific heat of silver, c = 0.235 J/g K

The heat required is given by

H = m x c x ΔT

H = 266 x 0.235 x 7.29 = 455.67 J

(b) Specific heat of iron, c = 0.449 J/g K

The heat required is given by

H = m x c x ΔT

H = 266 x 0.449 x 7.29 = 870.67 J

The heat required is given by

H = m x c x ΔT

H = 266 x 0.522 x 7.29 = 1012.23 J

What is the frequency of a microwave with a wavelength of 3.52 mm?

AlekseyPX

As per the question the wavelength of the microwave is given as 3.52 mm.

we are asked to calculate the frequency of the wave.

we know that microwave is a electromagnetic wave.

As per Clark Maxwell's electromagnetic theory ,every electromagnetic wave moves with a velocity equal to the velocity of light in vacuum and that is equal to 3×10^8 m/s.

From the equation of the wave,we know that velocity of wave is the product of frequency and wavelength.

Mathematically wave velocity $v=f*\lambda$ where f is the frequency of the wave and $\lambda$ is the wavelength.

As per the question $\lambda=3.52 mm$

$= 3.52*10^{-3} m$

Here $v=c=3*10^{8} m/s$

Hence frequency of the wave $f=\frac{v}{\lambda}$

$=\frac{3*10^{8} }{3.52*10^{-3} } s^{-1}$

$=0.852272727272*10^{11} Hz$

Here Hertz [Hz] is the unit of frequency.

Two steamrollers begin 115 mm apart and head toward each other, each at a constant speed of 1.10 m/sm/s . At the same instant, a

NeX [460]

Answer:

The distance of fly travel is 115.06 m.

Explanation:

Given that,

Distance = 115 mm

Speed = 1.10 m/s

Speed of fly = 2.20 m/s

We need to calculate the relative speed

Using formula of relative speed

$v=v_{1}+v_{2}$

Put the value into the formula

$v=1.10+1.10$

$v=2.20\ m/s$

We need to calculate the time for the two steamrollers to meet each other

Using formula of time

$t=\dfrac{d}{v}$

Put the value into the formula

$t=\dfrac{115}{2.20}$

$t=52.3\ sec$

We need to calculate the distance of fly travel

Using formula of distance

$d=vt$

Put the value into the formula

$d=2.20\times52.3$

$d=115.06\ m$

Hence, The distance of fly travel is 115.06 m.
