We use the formula,
.
Here, v is velocity and its value given 26 mi/h ( in m/s, ) and d is distance and its value is given 80 m.
Substituting these values in above formula we get,
Thus, the time delay between green lights on successive blocks to keep the traffic moving continuously is 6.88 s
The two elements would be element Y and element Z. They both have one valence electron. This means that their bonding properties would be similar because both of them can donate 1 electron. Since both of them have one valence electron, one can assume that they also belong in the same group.
Answer:
T = 2390 degree C
Explanation:
Given data:
Resistance 12 ohm
Temperature 20 degree C
we know that linear relation between the resistance and temperature is given as
where is resistance at and = coefficient of resistivity
SOLVING FOR
degree C
WE KNOW
T = 2370 + 20
T = 2390 degree C
The answer is "A magnetic field influences the motion of charged particles. The negatively-charged particles will experience a force acting against their motion, so the negatively-charged particles would slow down and stop moving."
This is because for example;
Have you ever seen a magnet? If so, you would experience the same scienario as above.
