Since like poles repel, the two horseshoe magnets have like poles facing each other, hence they repel each other and therefore they will not come in contact
Density = mass / volume
D = 89 / 10.0
D = 8.9 g/cm³
hope this helps!
Answer:
b. Increasing the mass of the arrow.
Explanation:
The formula is K=1/2mv^2. Increasing the mass also increases the kinetic energy.
Answer:
Energy stored, E = 0.072 J
Explanation:
Given that,
Capacitance, 
Capacitance, 
These two capacitor are connected in parallel, and charged to a potential difference of, V = 60 volts
We know that in parallel combination of capacitor, the equivalent capacitance is given by :

The energy stored in the capacitor is given by :

So, the energy stored in the capacitor in this capacitor combination is 0.072 J.
