Answer:
well the the answer to the hypossis is that i think the pencil will leave a mark on my finger.
observation the indent will be there for a little if i do not press hard harder i press the longer the mark stay what made this diffrence is that my hypossis got somthing wrong. the thumb will not leave a mark that you can barly see and the index finger has visble mark because the end of the pincel shaper
and pionty and the eares side is flay so i barly leaves a mark
Explanation:
Explanation:
The aircraft is traveling north at 100 m/s.
The wind blows from the west (towards the east) at 25 m/s.
The two vectors form a right triangle. The magnitude of the resultant velocity can be found with Pythagorean theorem:
v² = vx² + vy²
v² = (25 m/s)² + (100 m/s)²
v = 103 m/s
The direction can be found with trigonometry:
θ = atan(vy / vx)
θ = atan(100 / 25)
θ = 76.0°
The resultant velocity is 103 m/s at 76.0° north of east.
Answer: A. Study conceptually the nature of the electric charge and force
Explanation: Since the electrons are the mobile charge carriers, they will therefore be the particles that are transferred. For this case, since the electrophorus is positively- charged, the electrons from the sphere will be attracted to the electrophorus and thus will be transfer there.
Answer:
The charge must be on each plate is .
Explanation:
Given that,
Electric field
Area = 2500 cm²
Distance = 0.10 mm
We need to calculate the potential difference
Using formula of potential difference
We need to calculate the capacitor
Using formula of capacitor
Put the value into the formula
We need to calculate the charge
Using formula of charge
Hence, The charge must be on each plate is .
