Answer:
1. 
2. 
3. 
4. α = 59.05°
5.
6. α = 59.05°
Explanation:
The position of the center of mass 1s before the collision is:
where
; 
;
; 
;
Replacing these values:
where
; ;
; ;
Replacing these values:
The velocity of their center of mass is:
where
; ;
; ;
Replacing these values:
where
; ;
; ;
Replacing these values:
So, the magnitude of the velocity is:
The angle of the velocity is:
Since on any collision, the velocity of the center of mass is preserved, then the velocity after the collision is the same as the previously calculated value of 16.66m/s at 59.0° due north of east
Answer:True
Explanation:
The above statement is true as an anti-lock braking system (ABS) is a vehicle protection system that helps the wheels on a vehicle to keep up tractive force with the road. ABS does not allow the brake to lock during braking and thus avoiding skidding which is necessary to avoid in wet roads otherwise it could be fatal for drivers.
It is widely used in vehicles to improve the safety measures and reduce road accidents.
Hello there,
The word 'repeatable' means, the scientific experiment is repeated in the same way, with the same methods and analysis.
Hope this helps :))

1.1 A. An electric oven with a resistance of 201Ω and a voltage of 220V drwa a current of 1.1 A.
The easiest way to solve this problem is using the Ohm's Law I = V/R.
An electric oven has R = 201Ω, and a drop of voltage V = 220v, solve using I = V/R:
I = 220V / 201Ω
I = 1.09 A ≅ 1.1 A
