The answer would be a radio wave
Answer:
Explanation:
Lattice energy is the energy required to separate one mole of an ionic solid compound into its components gaseous cations and anions.
Due to increase in size of the ions, the lattice energy decreases while the lattice energy increases as the charge of the ions increases.
When the size increase, the distance between the nuclei also increase leading a decrease the force of attraction between the nuclei
Given the speed and the distance, to find time you can use the formula speed is equal to distance over time. From there you can manipulate the equation for time to equal the distance divided by speed. Time is equal to 18.4 meters divided by 35m/s which equals 0.526 seconds.
Answer:
Explanation:
Impulse results in change of momentum
FΔt = mΔv
F = 0.030(50.0 - 0) / 0.010 = 150 N
The vertical portion of that force adds to his weight on the ice
Fmax = 60.00(9.81) + 150sin30 = 663.6 N
As this is above the ice strength, He takes a cold dip.
In order to answer this, you can use this formula :
F = m.a
which means
a = F/m
a = 18N / 2kg
a = 9 N/kg or 9m/s2
hope this helps
