Answer:
Balanced forces do not result in any change in motion. forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion.
Explanation:
Answer:
<h2>31km/h</h2>
Explanation:
Step one:
given data
speed of bus= 35km/h forward
speed of ball= 4km/h backwards
`Step two:
Required
the magnitude of the velocity of the ball relative to the ground is the net velocity
that is
=35-4
=31km/h
<em><u>The velocity of the ball relative to the ground is 31km/h</u></em>
Answer:
im means into
e means out of
Explanation:
Using the definitions of immigration and emigration as points of reference, the following explanation applies.
Both terms are derived from migration which means moving from one place to another.
By further explanation:
The "im" in the definition of immigration means "into" while the "e" in the definition of emigration means "out of"
Answer:
Object will float.
Explanation:
Total force on the body = Weight of body + Buoyancy force on body.
Weight of body = 15 N downwards = 15 N
Buoyancy force on body = 17 N upwards = -17 N
Total force on body = 15 - 17 = -2 N = 2 N upwards
So, the body will float.
Object will float.
Vf = final velocity
vo = initial velocity
a = acceleration
t = time
use the following equation
vf = vo + at
since vo = 0 m/s (stopped), that term drops out and you're left with . . .
vf = at
(60 m/s) = (8.0 m/s²)t
t = (60 m/s)/(8.0 m/s²) = 7.5 seconds
<u><em>t = 7.5 seconds</em></u>
