Answer:
The minimum thickness is
Explanation:
generally the equation for thin film interference is mathematically represented as
Where t the thickness
m is any integer
n is the refractive index of the film
is the wavelength of light
Since we are looking for the thickness we make t the subject of the formula
m= 0 cause the thickness is minimum at m=0
Substituting values
Answer:
Newton's third law of motion.
Explanation:
An ice skater at rest pushes against a sled at rest,causing both the skater and sled to move away from each other with different acceleration. It is based on Newton's third law of motion.
Third law says that, for every action there is an equal; and opposite reaction. Here, action is force applied by ice skater and reaction is motion of skater and sled away from each other with different acceleration.
Answer:
313.6N
Explanation:
Given parameters;
Mass of the body = 50kg
Coefficient of friction = 0.64
Acceleration due to gravity = 9.81m/s²
Unknown:
Minimum force needed to move the body = ?
Solution:
To move this body, the minimum force must overcome the frictional force. So, the value of force that equals to that of the frictional force will set the body in motion.
Frictional force = Umg
U is the coefficient of friction
m is the mass
g is the acceleration due to gravity
Now insert the parameters and solve;
Frictional force = 0.64 x 50 x 9.8 = 313.6N
Answer:
a. much stronger than that of Earth and greatly extended.
Explanation:
Jupiter is a gas giant. It mainly consists of hydrogen and helium and also may have rocky core. Jupiter has the fastest rotational period among the planets of the solar system. One day on Jupiter lasts for 11 hours. This rotation causes the hydrogen in the atmosphere to rotate at great speed.
The rotation of the hydrogen generates the magnetic field of Jupiter. It is almost 14 times greater than the Earth's magnetic field in terms of strength and the second largest in terms of distance after the sun.
