Answer:
5 N right
Explanation:
Fx = 9N-4N
Fx = 5N
Since we can define the x and y axis. We have x to the right as positive.
In the second 30 mins, the speed should be 20 + 1.5 = 21.5 km/h
So S = 21.5 * 30/60 = 10.75 km
What is the magnitude of force required to accelerate a car of mass 1.7 × 10³ kg by 4.75 m/s²
Answer:
F = 8.075 N
Explanation:
Formula for force is;
F = ma
Where;
m is mass
a is acceleration
F = 1.7 × 10³ × 4.75
F = 8.075 N
Es el conjunto de longitudes de onda de todas las radiaciones electromagnéticas
Answer:
1.1 V
Explanation:
L = 0.45 m
d = 0.11 m
B = 0.80 T
t = 0.036 s
Let e be the emf.
e = B v L
e = 0.80 x 0.11 x 0.45 / 0.036 = 1.1 V
