The passing of heat through a material while the material itself stays in place is conduction.
<span>When the question says the ball lands a distance of 235 meters from the release point, we can assume this means the horizontal distance is 235 meters.
Let's calculate the time for the ball to fall 235 meters to the ground.
y = (1/2)gt^2
t^2 = 2y / g
t = sqrt{ 2y / g }
t = sqrt{ (2) (235 m) / (9.81 m/s^2) }
t = 6.9217 s
We can use the time t to find the horizontal speed.
v = d / t
v = 235 m / 6.9217 s
v = 33.95 m/s
Since the horizontal speed is the speed of the plane, the speed of the plane is 33.95 m/s</span>
Answer:
The answer is A - Newtons First Law
Explanation:
The law is what we call "Inertia". The law basically states that an object wants to stay where it is. We can see the effect from our cars, albeit with less force. When the car turns right, your body goes left, opposite to the turns direction due to us moving position in the car.
Answer:
Cesium has smallest ionization energy.
Explanation:
Ionization energy is the energy that an atom at ground state must be absorb to release an electron to form a cation. for eg.
H ⇒ 
The unit of ionization energy is 
.
The ionization energy is minimum for cesium & maximum for fluorine.
Ionization energy depends upon the radius of atom. cesium has smallest radius so it has low Ionization energy.
Therefore the cesium has smallest ionization energy.
