Your calculator will return a result of 11.76cm^2
The correct answer must have 2 significant figures:
Answer : 12cm^2
<u>Given that</u>
time (t) = 10 s ,
(S) = ?
We know that S = ut+ 1/2 a.t² m
since free fall and no air friction,
a = g = 9.81 m/s² ; initial velocity u= 0
S = 0 + [1/2 × 9.81 ×10²]
<em> S = 490.5 m </em>
Answer:
a = 2.22 [m/s^2]
Explanation:
First we have to convert from kilometers per hour to meters per second
We have to use the following kinematics equation:
where:
Vf = final velocity = 11.11 [m/s]
Vi = initial velocity = 0
a = acceleration [m/s^2]
t = time = 5 [s]
The initial speed is taken as zero, as the car starts from zero.
11.11 = 0 + (a*5)
a = 2.22 [m/s^2]
Answer:
1.2kV
Explanation:
We are given that
Linear charge density,
We have to find the potential difference between poinst 5.0 m and 6.0 m from the wire.
We know that potential difference of wire
Where
Substitute the values
1kV=1000 V
D Waves W and X are transverse waves, Wave Y could be a longitudinal or transverse wave, and Wave Z is a longitudinal wave. Just took the test on edge it's a cumulative exam
