Answer:
Explanation:
Acceleration is the rate of change of an object with respect to time. It is the change in velocity over the time.
The car starts at 10 meters per second and increases to 20 meters per second in 2.5 seconds.
- = 20 m/s
- = 10 m/s
- t= 2.5 s
Substitute the values into the formula.
Solve the numerator.
Divide.
The acceleration of the car is <u>4 meters per second squared.</u>
Answer:
a) x = 0.200 m
b)E = 3.84*10^{-4} N/C
Explanation:
DISTANCE BETWEEN BOTH POINT CHARGE = 0.5 m
by relation for electric field we have following relation
according to question E = 0
FROM FIGURE
x is the distance from left point charge where electric field is zero
solving for x we get
x = 0.200 m
b)electric field at half way mean x =0.25
E = 3.84*10^{-4} N/C
Answer:
the 3 one is the answer the length of the wire in the magnetic
Answer:100joules
Explanation:
Mass(m)=5kg
Acceleration due to gravity(g)=10m/s^2
Height(h)=2 meters
Work=m x g x h
Work=5 x 10 x 2
Work=100joules
Average acceleration is how much the car increases (on average) per second. So, since it increases by 30 m/s in 8 s, then dividing 30 by 8 will give you an average acceleration of 3.75 m/s^2 (remember that acceleration is ever increasing, so the unit is s^2, not just s)
Hope this helps!
