Answer:
R = 73.25 m
Explanation:
We have,
Initial speed of the ball is 27 m/s
It is projected at an angle of 40 degrees
The maximum range of the ball is given by :

Plugging all the values we get :

So, the maximum range of the ball is 73.25 m
- Coefficient of static friction = 0.5
- Coefficient of Kinetic friction = 0.3
- Angular velocity = 500 RPMs
<h3>The Radius of the System</h3>
Let R be the radius of cylinder

The angular velocity is 500 RPMs

The normal force

Since the radius is very little for two block to execute circular motion so system will slide down.

Answer:
The correct answer is C.
Clarify any confusing information in the instructions.
Explanation:
The very first thing that we need before conducting a scientific investigation is a set of instructions which might include the following information:
-What we are experimenting on?
-How are we going to do it?
-What things are needed for it?
If there are any confusions in the instructions, the chances of making a mistake rises. So, it is very important to clarify the confusions found in the instructions before choosing things needed for the experiment and starting the experiment.
Answer:
<em>20cm</em>
Explanation:
<em>A coil wire comprises of 5 turns, it has a current of 2mA </em>
<em>A net magnetic field at the center of B is equal to Mu over 40 end fractions times T</em>
<em>The radius of a coil of wire with N turns is r = 0.28 m. A clockwise current of Icoil = 1.0 A flows in the coil,</em>
<em>Therefore 40/2mA = 20</em>
<h3><u>WWF in protection of Turtle eggs:</u></h3>
World Wildlife Fund (WWF) is an NGO that primly aims wildlife preservation. To protect marine turtles and avoid its poaching, WWF works through TRAFFIC, the Wildlife trade monitoring network.
Turtle eggs are highly demanded for human consumption, either raw or as expensive dishes in star rated restaurants. WWF along with TRAFFIC promotes ecotourism by raising awareness to stop preferring turtle products. It establishes and strengthens MPA's (Marine Protected areas) areas where turtle nesting is primarily observed and thus turtles are free and safe to nest, feed and migrate.
