Electrical Charge is a property of matter that causes it to experience a force when place in an electromagnetic field. Charge is measured in coulombs.
The change in the charge is 2.2- (2.0)= 4.2 μ c.
1 electron has a charge of 1.6 ×10∧-19 coulombs
Therefore, the number of electrons will be;
= (4.2 ×10∧-6)/ (1.6 ×10∧-19)
= 2.625 × 10∧13 electrons
Answer:
Explanation:
Let time taken by Jada in driving be t hour .
distance travelled by jada = 55 t
a )
Time of drive by destiny = t - 10 min
= t - .167 hour
distance of travel by destiny = 70 ( t - .167 )
Total distance = 45 miles
55 t + 70 ( t - .167 ) = 45
55t + 70 t - 11.69 = 45
125 t = 56.69
t = .453 hour = 27.21 minutes
b )
distance travelled by Destiny = 70 ( t - .167 )
70 ( .453 - .167 )
= 20.02 miles .
1.) Power, P = V²/R = 800²/45 = 4.5 W (A).
2.) Six Resistors in Series.
R = R1 + R2 + R3 + R4 + R5 + R6, Since R is the same, R = 20
R total = 6*20 = 120 (D)
3.) It is the current. Series connection is to evaluate current. (B)
Acoustic Energy
Sonar uses the echo principle by sending out sound waves underwater or through the human body to locate objects
Explanation:
The speed of an object can be found from the slope of the line which plots its distance over time. The object in motion's speed can be compared with another by the value of the slope or the steepness of the line. The steeper the slope is, the greater the speed.
