Answer:
The range of the projectile is 66.7 meters.
Explanation:
The range of a projectile is given by the following expression as :
..............(1)
The range can be calculated using equation (1). Putting the values of all parameters we get :
R = 66.7 meters
So, the range of the projectile is 66.7 meters. Hence, this is the required solution.
Answer:
Explanation:
Ionic bonding is stronger than any of the given intermolecular forces, but is itself NOT an intermolecular force. Ionic bonds are a permanent chemical connection between two atoms, whereas intermolecular forces as a more transient and temporary attraction between independent molecules
The metallic bond is somewhat weaker than the ionic and covalent bond. Ionic bonds are strong electrostatic attraction forces formed between positive and negative ions. This bond is non-directional, meaning that the pull of the electrons does not favor one atom over another.
Ion-dipole forces are the strongest of the intermolecular forces. ... However, hydrogen bonds are still not as strong as ion-dipole interactions. In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.
Van der Waals forces are driven by induced electrical interactions between two or more atoms or molecules that are very close to each other. Van der Waals interaction is the weakest of all intermolecular attractions between molecules
Planck's constant is 4.39048042 × 10-67 m4 kg2 / s2.
Capacitance,C is equal to epsilon times area of the plate divided by distance. The permittivity of air is 8.84 x 10-12 F/m. Capacitance is equal to 2.66 x10^14 F. The energy is equal to 0.5* C*V^2. Substituting, the energy is equal to 0.5* <span> 2.66 x10^14 F * 6^2 V^2 or equal to 4.80 x10^15 W.</span>
