car starts from rest
![v_i = 0](https://tex.z-dn.net/?f=v_i%20%3D%200)
final speed attained by the car is
![v_f = 5 m/s](https://tex.z-dn.net/?f=v_f%20%3D%205%20m%2Fs)
acceleration of the car will be
![a = 3.6 m/s^2](https://tex.z-dn.net/?f=a%20%3D%203.6%20m%2Fs%5E2)
now the time to reach this final speed will be
![t = \frac{v_f - v_i}{a}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7Bv_f%20-%20v_i%7D%7Ba%7D)
![t = \frac{5 - 0}{3.6}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B5%20-%200%7D%7B3.6%7D)
![t = 1.39 s](https://tex.z-dn.net/?f=t%20%3D%201.39%20s)
so it required 1.39 s to reach this final speed
Answer:
Explanation:
Same numbers of protons but different number of neutron so i would go for A same atomic number different number of neutrons
Answer:
E = I(R + r)
Making I the subject of the formular by dividing both sides by R + r,
I = E/(R + r)
E = 4V, r = 0.7Ohm, R = 0
I = 4/(0 + 0.7) = 4/0.7
I = 5.174285714A
Explanation:
For a cell of emf E, internal resistance r, connected to an external resistance R, the current flowing through the circuit will be given as:
I = E/(R + r). I is measured in Amperes(A), emf in volts(V), R in Ohms and internal resistance r also in ohms
