Answer: When you cannot stop safely at a yellow traffic light before entering an intersection, enter the intersection carefully and continue across.
Explanation: To find the correct answer, we need to know more about the traffic signal rules.
<h3>What is the traffic signal rules?</h3>
- Red light- Indicator for the motorists to stop.
- Green-Signal for safety and word GO.
- Yellow- This signal let you know that the red signal is about to be displayed.
- when it's turned on, you can start slowing down to come to a stop in anticipation of red light.
- when we cannot stop safely at a yellow traffic light before entering an intersection, enter the intersection carefully and continue across.
Thus, we can conclude that, the option C is correct.

Answer:
They lie on the Ecliptic (apparent path of the Sun around Earth)
Explanation:
There are total 88 constellations in the sky out of which only 12 are considered as zodiacal constellations or Sun signs. This is because these are the constellations which lie on the Ecliptic.
Ecliptic is the apparent path of Sun around the Earth.
In other words, it can be said that the Sun appears to reside in 12 constellations throughout the year as the Earth revolves around it.
Answer:
0.2631 N/C
Explanation:
Given that:
The radius of the wire r = 0.22 mm = 0.22 × 10⁻³ m
The radius of the thick wire r' = 0.55 mm = 0.55 × 10⁻³ m
The numbers of electrons passing through B, N = 6.0 × 10¹⁸ electrons
Electron mobility μ = 6.0 x 10-4 (m/s)/(N/C)
= 0.0006
The number of electron flow per second is calculated as follows:




The magnitude of the electric field is:
E = 
E = 
E = 
E = 0.2631 N/C
Answer:
The horizontal distance d does the ball travel before landing is 1.72 m.
Explanation:
Given that,
Height of ramp 
Height of bottom of ramp 
Diameter = 0.17 m
Suppose we need to calculate the horizontal distance d does the ball travel before landing?
We need to calculate the time
Using equation of motion




We need to calculate the velocity of the ball
Using formula of kinetic energy



Using conservation of energy



Put the value into the formula


We need to calculate the horizontal distance d does the ball travel before landing
Using formula of distance

Where. d = distance
t = time
v = velocity
Put the value into the formula


Hence, The horizontal distance d does the ball travel before landing is 1.72 m.
Explanation:
Given that,
Force constant of the spring, k = 120 N/m
Frequency of vibration, f = 6 Hz
Solution,
(a) Let T is the time period of the spring. The relation between the frequency and the time period is given by :


T = 0.167 s
(b) Let
is the angular frequency. It is given by :



(c) The relation between angular frequency and the spring constant is given by :



m = 0.084 kg
or m = 84 grams
Therefore, it is the required solution.
