A stone has a mass of 100 grams and a volume of 10ml water has a density of 1 g/ml will the stone sink or float?
JulsSmile [24]
Density = Mass / Volume 

Density of stone = 100 / 10 = 10 g/mL

If the density is higher than water, then the object will sink. If the density of the object is lower than water, then the object will float. 

Since the density of the rock is 10g/mL and the density of the water is 1g/mL, the stone will sink.

Lamp power with 120 W what is the current through the lamp when it is connected to a 12 V battery ?
SVETLANKA909090 [29]

Answer:

current = 10A

Explanation:

recall the formula, Power = current * voltage

                              120 W  = current * 12V

                               current (A) = 120 W / 12V

                               current = 10A

<h3>What are electric conductors?</h3>

Conductors are materials that allow electric current to pass through them.

<h3>What are Insulators?</h3>

Insulators are materials that do not allow electric current to pass through them.

<h3>Examples of conductors</h3>
  • Metal doorknob
  • Silver
  • Gold
  • Copper
  • Metal coat hanger
  • Paper clip
<h3>Examples of insulators</h3>
  • Carpet
  • Wood
  • Rubber

A ball of mass 2.0 kg falls vertically and hits the ground with speed 7.0 ms-1 as shown below.
Sauron [17]

Answer:

8.0 Ns

Explanation:

Change in momentum is given as:

Final momentum - Initial momentum

= m*v - m*u

Where m = mass of ball

v = final velocity

u = initial velocity

Change in momentum = (2.0 * 3.0) - (2.0 * 7.0)

= 6.0 - 14.0 = -8.0 Ns

The magnitude will be |-8.0| = 8.0 Ns
