Answer:
I think we should use supersaturated solution
Here, you need to use your "Protractor" as it is given in the question, but we can calculate the value with the help of our mathematical calculation too:
[ Protractor can be use only in real life, not here ]
Draw an imaginary line from initial position to final position.
Now, In that triangle, tan x = P/B
tan x = 1.4 / 2
tan x = 0.70
x = tan⁻¹ (0.70)
x = 35 [ tan 35 = 0.70 ]
In short, Your Answer would be 35 degrees
Hope this helps!
Answer:
A
Explanation:
because both energy and temperature ️ increase both are related.
Answer:
We have been given that car is moving 60 km in east
And 90 km in west
That means we are given two different directions
So, if distance in East is taken to be positive 60 km
Then the distance when car is moving in west direction will be taken as -90 km
So, the displacement means how far the object is from to initial to final position.
So, the displacement will be (-90)+60 = -30
So, it will be in -30 km (minus is west direction).
Answer:
The velocity of the boy and the bicycle is 2.2 m/s.
Explanation:
We have,
Mass of child is 30 kg and the mass of bicycle is 20 kg. The combined momentum of the child and the bicycle is 110 kg-m/s.
It is required to find the velocity of the boy and the bicycle. The momentum of an object is given in terms of mass and its velocity. So,

M is combined mass of child and bicycle

So, the velocity of the boy and the bicycle is 2.2 m/s.
