with your data:
1250 N of force is required to accelerate a 250 kg motorcycle at a rate of 5 m/.
<u>Explanation:</u>
As per the second law of motion stated by Newton, the net unbalanced external force acting on any object is directly proportional to the product of mass and acceleration experienced by the object.
As here the object is given as motorcycle of mass 250 kg. Also the acceleration exhibited by the motorcycle is stated as 5 m/. So from the Newton's second law of motion,
Net force = Mass of the motorcycle× Acceleration of the motorcycle
Net force = 250 × 5 = 1250 N.
Thus, 1250 N of force is required to accelerate a 250 kg motorcycle at a rate of 5 m/.
To solve this problem we will apply the concepts related to resistance as a function of temperature, product of the relationship between the squared voltage and the power. Mathematically this is,
Here,
R = Resistance (At function of temperature)
v = Voltage
P = Power
Then we have,
R at 140°C (7 times room temperature),
The relationship between normal temperature and increased temperature would then be given by,
Therefore the correct value of the group of answer is 1350
