Answer:
the mass and pen..............
Answer:
Both technician are correct.
Explanation:
Remember that Ohm's Law its a relationship between Voltage (E), Current (I) and Resistance (R) in an electrical circuit. This relationship is defined by the following equation:
V=IR
In Ohm's Law you have 3 variables (V,I,R) and 1 equation. It means that you need to know 2 variables (Whatever 2 variables) to know the third.
Technician A says, in other words, that could calculate the Circuit current flow (I) knowing total circuit resistance (R) and total voltage (E). Note that Technician A knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:
Technician B says, in other words, that could determine the unknown resistance (R) knowing total current (I) and source voltage (E). Once again, note that Technician B knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:
Answer:
Let the volume of the cube be V and the fraction of cube outside water be f.
Thus, volume of ice inside water = volume of water displaced =(1−f)V
Under equilibrium,
Weight of ice = Weight of water displaced
⟹Vρ
ice
g=(1−f)Vρ
water
g
⟹(1−f)=

9
⟹f=

1
Thus, the percentage of volume outside water =10%
Answer:
1.4 m/s
Explanation:
The final velocity of the ball can be found by using the following SUVAT equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
d is the distance travelled
In this problem,
u = 4.0 m/s
d = 14 m
a = -0.50 m/s^2
Solving the equation for v,
