Answer: Deviation in physics means the measure of variations of N points and it's average value. To simple terms, it means the difference between a value of an measurement or a observation.
If this is the normal deviation word, it just means that you are doing something out the ordinary that doesn't seem normal or acceptable at all.
Answer:
The fish gobbles the mosquito at height 18 cm.
Explanation:
Initial velocity, u = 3.7 m/s
horizontal distance, d = 28 cm
Angle, A = 39 degree
Let the time is t.
Horizontal distance = horizontal velocity x time
d = u cos A x t
0.28 = 3.7 cos 39 x t
t = 0.097 s
Let the height is h.
Use the second equation of motion
Answer:
41.27m/s
Explanation:
According to law of conservation of momentum
m1u1+m2u2 = (m1+m2)v
m1 and m2 are the masses
u1 and u2 are the initial velocities
v is the velocity after impact
Given
m1 = 0.2kg
u1 = 43.7m/s
m2 = 45.9g = 0.0459kg
u2 = 30.7m/s
Required
Velocity after impact v
Substitute the given parameters into the formula
0.2(43.7)+0.0459(30.7) = (0.2+0.0459)v
8.74+1.409 = 0.2459v
10.149 = 0.2459v
v = 10.149/0.2459
v = 41.27m/s
Hence the speed of the golf ball immediately after impact is 41.27m/s
Answer:
1 DC
2 DC
3 DC
4 AC
5 DC
Explanation:
AC means alternating current this type of current is not constant I.e time varying
This type of current is being supplied from power lines
DC means direct current and flows at a constant direction. This type of current is being supplied from batteries.
