3 +250= 253 take 253 dived it by 3 ,subtract 4 =80.3
Answer:
what you do on one side you do on the other
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
change the signs on both sides of the equation
7-4x= - 9
move constant to the right side and change its sign
- 4x = - 9 - 7
-4x= - 16
divide both sides of the equation by -4
x = 4
Answer:
bring each tube close to the plastic ball and note any movement of the ball
Step-by-step explanation:
Electric fields can exert forces on objects, even if the objects involved are not touching. One way to demonstrate that electric fields exist around charged objects is to observe the effects of their forces at a distance.
Since the plastic ball of the electroscope is made of insulating plastic and is uncharged, it will be attracted to any charged object brought near it. So Jen can observe the effects of the tube's electric fields by bringing each tube close to the plastic ball and noting any movement of the ball. If the ball moves toward a tube, then the process that Jen used on the tube generated an electric field.
Answer: 158.26cm³
Step-by-step explanation:
First, we.need to calculate the volume of the cylinder and this will be:
Volume = πr²h
Volume = 3.14 × 3² × 8
Volume = 3.14 × 9 × 8
Volume = 226.08cm³
Since the jar is 70% full, the volume will be:
= 70% × 226.08cm³
= 0.7 × 226.08cm³
= 158.26cm³
Note:
Radius = Diameter/2 = 6cm/2 = 3cm
