Answer:
Maximum height will be 
Explanation:
We have given initial velocity through which basketball is thrown 
Acceleration due to gravity 
At maximum height velocity will be zero
So final velocity v = 0 m /sec
According to third equation of motion 
( Negative sign is due to upward acceleration )

Answer:
we see it is a linear relationship.
Explanation:
The magnetic flux is u solenoid is
B = μ₀ N/L I
where N is the number of loops, L the length and I the current
By applying this expression to our case we have that the current is the same in all cases and we can assume the constant length. Consequently we see that the magnitude of the magnetic field decreases with the number of loops
B = (μ₀ I / L) N
the amount between paracentesis constant, in the case of 4 loop the field is worth
B = cte 4
N B
4 4 cte
3 3 cte
2 2 cte
1 1 cte
as we see it is a linear relationship.
In addition, this effect for such a small number of turns the direction of the field that is parallel to the normal of the lines will oscillate,
Answer:
The horizontal component is zero.
The vertical component is 
Explanation:
Given that,
The lizard climb 7m directly up on a tree.
We know that,
The horizontal component is

The vertical component is

If the lizard climb 7m directly up on a tree then,
We need to find the components
Using given data
The horizontal component of lizard is

The vertical component is

Hence, The horizontal component is zero.
The vertical component is

➷ Earth's gravity is approximately 9.81
weight = mass x gravity
weight = 4.6 x 9.81
weight = 45.126
