Answer:
Both are moving at 30 km/h, so their speed is the same. ... enough fuel for the trip/how long it will take. 4 Weight is a force, and so is a vector. ... c At 10 seconds David's displacement is.
Answer:
Explanation:
current (I) = 0.12 A
potential difference (v) = 3 volt
now
resistance (R)
= V / I
= 3 / 0.12
= 25 Ω.
hope it will help :)
Answer:15th
Explanation:
I believe it will fall on the 15th stair because 10 times 15 is 150 divided by 10 m/s equals 15
maximum allowed value of the speed in roller coaster is given as
now from kinematics we can say
here initial speed will be
acceleration is due to gravity
now we can use this to find the height
so maximum allowed height will be 20.4 m
Answer:27.35 s
