Answer:
This ball will attain the same range at 60°.
Explanation:
Projectile motion: when an object is thrown in such a way that it form an angle with horizon, the force act on it that is the acceleration due gravity. This type of motion is known as projectile motion.
Range: The horizontal distance is covered by an object.
Range
u = initial velocity = 40 m/s
θ = 30°
g = gravity =9.8 m/s²
Next,
Range and u = 40 m/s
This ball will attain the same range at 60°.
The velocity of the air relative to the ground is
The velocity of the plane relative to the air is
where is the direction the plane needs to point so that the resultant vector - the velocity of the plane relative to the ground - is
Here is the speed of the plane relative to the ground.
So we have
Use a calculator to solve for and ; you should find
The potential difference between the two ends of the circuit is the electric potential difference. The electric potential difference and the work will be 10V and 1.6 x 10^-18 J respectively.
<h3>What is an electric field?</h3>
An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.
The given data in the problem is given by;
E is the electric field = (200 N/C)
d is the distance = 5.0 cm.=0.05 m
Q is the charge of electrons= 1.602 x 10^-19 C
The formula for electric potential is given by;
The work is defined as the product of the potential difference and charge of an electron.
Hence the electric potential difference and the work will be 10V and 1.6 x 10^-18 J respectively.

D. Gravitaional pulls from unseen galaxies, your correct.
This example illustrates statement-B.
If one side can't understand scientific arguments, or doesn't want to hear them, or doesn't want to think about anything that might change their mind, then statement-D is also illustrated in that case.
