Answer:
Science is the body of knowledge that explores the physical and natural world. Engineering is the application of knowledge in order to design, build and maintain a product or a process that solves a problem and fulfills a need.
Explanation:
Answer:
Explanation:
= Mass of the Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
r = Radius of Earth = 6371000 m
m = Mass of person
The force on the person will balance the gravitational force
The acceleration that the Earth will feel is
Answer:
The electric field is entering the sheet
Explanation:
When the electron enters the region with the two fields, each one feels a force, so that the direction of the electron is altered, the sum of these two forces is zero.
Let's look for the direction of the magnetic force, for a positive charge, using the rule of the right hand, where the thumb goes in the direction of the velocity of the particle, the fingers extended in the direction of the magnetic field and the palm is in the direction of the strength
Let us apply this rule our case, the thumb goes the x axis and the fingers on the Y axis, therefore, the force is coming out of the sheet, if the load were positive, but with negative the magnetic outside is entering the leaf
The electric force is F = q.E.
For the resultant to be zero the electric force must leave the sheet and as our charge is negative The electric field is entering the sheet
The speed of the wave is given by Distance divided by time.
Speed = 10.9/5.1
= 2.14 m/s
But; speed is also given by frequency multiplied by wavelength
Wavelength is 4 m( distance between two successive crests)
thus; 2.14 = 4 × f
f = 2.14/4
= 0.535 Hz
