Answer:
option C
Explanation:
given,
Temperature of the surface = 6000 K
using formula to calculate 

is the maximum wavelength emission in meter.
T is the temperature in kelvin.




the wavelength is in Visible range
The Correct answer is option C
The car's acceleration, given the data from the question is 4 m/s²
<h3>Data obtained from the question</h3>
The following data were obtained from the question:
- Initial velocity (u) = 13 m/s
- Distance (s) = 50 m
- Time (t) = 5 s
- Acceleration (a) = 9.8
<h3>How to determine the acceleration of the car</h3>
The acceleration of the car can be obtained as illustrated below:
s = ut + ½at²
50 = (0 × 5) + (½ × a × 5²)
50 = 0 + (½ × a × 25)
50 = 0 + 12.5a
50 = 12.5a
Divide both sides by 12.5
a = 50 /12.5
a = 4 m/s²
Thus, the acceleration of the car is 4 m/s²

Answer:
me too I can't understand
Answer:
The speed of the car after the break was applied is 90.46 m/s
Explanation:
Given;
initial velocity of the car, u = 26.8 m/s
accelertation of the car, a = -8.2 m/s²
time of motion, t = 14.3 s
final velocity, v = ?
Apply the following kinematic equation;
v = u + at
v = 26.8 + (-8.2 x 14.3)
v = 26.8 - 117.26
v = -90.46 m/s
magnitude of the final velocity = 90.46 m/s
Therefore, the speed of the car after the break was applied is 90.46 m/s
