Answer:
4 P
Explanation:
V = IR
when they are in series R = 2 r
when they are in parallel R = 1/2 r
so current will increase by a factor of 4 when they are in parallel
and power used will also increase by a factor of 4 to 4 P
Power = IV when I now becomes 4 I power becomes 4 P
Answer: 3rd option
Explanation: Since it has less mass and same force as other object it will have higher acceleration
Answer:
Design 2
Explanation:
I had this same question
My answer:
"Design 2 is the well-designed one, because the air molecules are the most compact and could protect the individual better than 1,3,and no air bag."
Answer:
a. 3.6 units
b. 1.4 units
c. 3.6 units
d. 6.1 units
Explanation:
The length of a vector is given by the following formula:
Length = √(x² + y²)
where,
x = x-component of vector
y = y-component of vector
a.
Here,
x = 2
y = 3
Therefore,
Length = √(2² + 3²)
Length = √13
<u>Length = 3.6 units</u>
<u />
b.
Here,
x = 1
y = 1
Therefore,
Length = √(1² + 1²)
Length = √2
<u>Length = 1.4 units</u>
<u />
c.
Here,
x = 2
y = -3
Therefore,
Length = √(2² + (-3)²)
Length = √13
<u>Length = 3.6 units</u>
<u />
d.
Here,
x = 1
y = -6
Therefore,
Length = √(1² + (-6)²)
Length = √37
<u>Length = 6.1 units</u>
The earth has an atmosphere that disintegrates most meteorites that make craters, unlike the moon, which has no atmosphere and nothing to protect it from meteorites
