Explanation:
It is given that,
Length of the copper wire, l = 4.4 m
Diameter of copper wire, d = 1.3 mm = 0.0013 m
Radius of copper wire, r = 0.00065 m
The resistivity of the copper wire,
We need to find the resistance of the copper wire. It is given by :
R =0.055 ohms
So, the resistance of the copper wire is 0.055 ohms. Hence, this is the required solution.
Explanation:
It is given that,
Velocity of particle 1, u₁ = 10 m/s
Velocity of particle 2, u₂ = 5 m/s
Let v₁ and v₂ are the final speed of both particles after the collision. Applying the conservation of momentum as :
......................(1)
For an elastic collision, the coefficient of restitution is equal to 1 as :
................(2)
On solving equation (1) and (2), we get,
So, the speeds of particle 1 and particle 2 after the collision is 5 m/s and 10 m/s respectively. Hence, this is the required solution.
Answer:
Height of the balloon is 6.923 miles or 11141.46m
Explanation:
We form two triangles with a common vertex so the relation of the angles is and the position both are measuring
The second triangle have the mileposts on the road that is a mile more so:
Now resolve the both equation to know the opposite side that is the height of the hot air balloon
Height=6.923miles
Leigth can be find also
The measure can be express in meters so
