Answer:
Explanation:
The De Broglie's wavelength of an object is given by:
where
h is the Planck constant
m is the mass of the object
v is the speed of the object
In this problem, we have:
is the mass of the pellet
is the speed of the pellet
Substituting into the equation, we find the wavelength of the pellet:
A line of dominoes falling one by one is an example of energy transfer. Energy is defined as the capacity to do work.
Answer:
Explanation:
The resultant velocity of the motorboat due to the current perpendicular to the motion of the boat can be calculated by drawing a triangle to represent this motion. The velocity of the motorboat is the base whereas the velocity of the river is the perpendicular of the triangle (picture attached).
The angle is (perpendicular/base);
(5/20)= 14.0;
The triangle can be enlarged such that the perpendicular now represents the width of the river and the perpendicular represents the distance between the dock and landing place.
The distance between dock and landing place is:
a) base*Tan(∅) = 2*Tan(14) = 0.5km
b Time = 2/20= 0.1 hours. This is because the horizontal component of the motion due to velocity of motor boat will be considered for horizontal distance of 2 km.
