Answer:
Option (a) The fan turns electrical energy into energy of motion.
Explanation:
A fan is a device which operates on electric current. It receives electrical energy and transform it to rotational motion(i.e motion about a fixed point)
Answer: option C) 3.0
Explanation:
The electronegative value of an element indicates the power of its atom to attract an electron. It ranges from 0 to 4.
Ionic bond is formed between two elements with WIDE difference in electronegative values. e.g Sodium with 0.93 and Chlorine with 3.16 forms an ionic bond in NaCl with a difference of 2.23
Thus, a difference of up to 3.0 makes an ionic bond
Answer:
1.5 hours or 90 minutes
Explanation:
Velocity = d/t
V = 64 mi / hour or 96 mi / 9 min OR 16 mi / 15 min
D = 96 miles
Velocity * Time = Distance
Time = Distance / Velocity
T = 96 mi / 64 mi / hour
96 / 64 = 1.5 mi per hour
T = 1.5 hours or 90 minutes
