Answer:

option C

Explanation:

given,

Temperature of the surface = 6000 K

using formula to calculate \lambda_{max}

\lambda_{max} = \dfrac{0.0029\ K.m}{T}

\lambda_{max} is the maximum wavelength emission in meter.

T is the temperature in kelvin.

\lambda_{max} = \dfrac{0.0029}{6000}

\lambda_{max} = \dfrac{0.0029}{6000}

\lambda_{max} = 4.8333 \times 10^{-7}

\lambda_{max} = 4833\ A^0

the wavelength is in Visible range

The Correct answer is option C

A speeding Thunderbird left skid marks on the road that were 76.7 m long when it came to a stop. If the acceleration of the car
FrozenT [24]

Answer: 39.2 m/s

Explanation:

You can use the kinematic equation:

v_f^2=v_i^2+2a*d

We know the final velocity because it says it came to a stop. So now all we gotta do is plug in.

0^2=v_i^2+2(-10)(76.7)\\v_i^2=1,534\\v_i=\sqrt{1534} \\=39.166 m/s

Is (kr) an element a compound or a mixture?
Xelga [282]

Krypton ... symbol Kr ... is an element.  It's element number 36, because
there are 36 protons in the nucleus of every atom of Krypton. 

Krypton has nothing to do with Superman, except that about 75 years ago,
the creators of Superman thought it was a cool-sounding scientific word,
so they chose it for the name of his home planet.

30. The length of mercury thread when it is at 0°C, 100°C and at an unknown temperature 0 is 25mm, 225mm and 175mm respectively.
yulyashka [42]

Answer:

75°C

Explanation:

175−25/225−25=x−0/100−0

150/200=x/100

x=150×100/200

= 75°C

Calculate the time (in seconds) needed for a car to accelerating from 0 m/s to 10 m/s at 5 m/s^2?
bazaltina [42]

Answer: 2 s

Explanation: In order to solve this problem we have to use the formule of the final speed  getting with a constant acceleration, it is given by;

Vfinal=Vo+a*t    where Vo is zero.

so then  t=Vfinal/a = (10 m/s)/5 m/s^2= 2 s

During a softball game, a batter hits a ball upward from an initial height of 3 feet. the height, in feet, of the softball is gi
Lynna [10]

Answer: 3.55 s and 0.83 s

Explanation:

The height (in feet) of the softball is given by:

s(t)=-16t²+70t+3

we need to find the time when the ball is 50 feet above the ground:

⇒50 = -16t²+70t+3

we need to solve the quadratic equation

⇒16t²-70t+47 = 0

t=\frac{70\pm \sqrt{70^2-4(16)(47)}}{2(16)}

This gives two values of time: 3.55 s and 0.83 s
