Answer:
For object A
m = 5 kg , v= -11 j
For B object
m = 6 kg , v= 5 i +8.7 j
For object C
m = 10 kg , v= -10 i
We know that
Linear momentum P= m v kg.m/s
a) A and C
Momentum in y direction
Py=- 5 x 11 j= - 55 j kg.m/s
Momentum in x direction
Px=- 10 x 10 j= - 100 i kg.m/s
b) B and C
Momentum in y direction
Py=6 x 8.7 j= 52.2 j kg.m/s
Momentum in x direction
Px=( 6 x 5 - 10 x 10 ) i = - 70 i kg.m/s
c) A ,B and C
By using data of a and b
Momentum in y direction
Py= 6 x 8.7 - 5 x 11 j= -2.8 j kg.m/s
Momentum in x direction
Px= 6 x 5 -10 x 10 i = -70 i kg.m/s
That would be gravitational force. Check out creation.com. Search up "star-formation" in their search bar. Hope this helped.
Answer:
C
Explanation:
Water at normal temperature is a good lubricant and will hinder the brake from working properly when the road is wet. To dry the brakes off, apply brakes gently as you accelerate. This will generate some heat that will evaporate the water with the help of friction.
Answer:
The value is
Explanation:
From the question we are told that
The radius of curvature is
Generally the radius of curvature is mathematically represented as

Here
is the focal length hence

Answer:
1500 milliradians
Explanation:
Data provided in the question:
1.5 radians
Now,
1 radians consists of 1000 milliradians
1 milli = 1000
thus for the 1.5 radians, we have
1.5 radians = 1.5 multiplied by 1000 milliradians
or
1.5 radians = 1500 milliradians
Hence, after the conversion
1.5 radians equals to the value 1500 milliradians
