Answer:
82.7 kg
Explanation:
the mass of the boxer remains unchanged, this is because mass is a measure of the quantity of matter in an object irrespective of its location and the gravitational force acting at its location. this means mass is independent of the gravitational acceleration hence it remains the same 82.7 kg. its unit is in kilograms (Kg).
Chlorine forms hydrochloric acid when reacted with hydrogen
velocity = distance / time v= d/t firstly you change 3000 m into km distance D = 3000/1000 = 3 km secondly time t = 21 min using velocity formula v = d/t = 3 km/21min =0.142km/min
Answer:
yeah righto the correct answer mate would be D) :)
Answer:
- magnitude : 1635.43 m
- Angle: 130°28'20'' north of east
Explanation:
First, we will find the Cartesian Representation of the and vectors. We can do this, using the formula
where its the magnitude of the vector and θ the angle. For we have:
where the unit vector points east, and points north. Now, the will be:
Now, taking the sum:
This is
Now, for the magnitude, we just have to take its length:
For its angle, as the vector lays in the second quadrant, we can use:
