Answer:
Explanation:
Cylinder P is taller than cylinder Q. In fact, it's twice as tall. So if cylinder Q is, let's say, 10 inches tall, cylinder P would be 20 inches tall.
Cylinder P is also wider, but not by a lot. It's only half as wide as cylinder Q. So if cylinder Q has a width of 10 inches, cylinder P would have a width of 5 inches.
Now, let's talk about the insides of these cylinders, how much stuff they can hold. If we filled them up with something, like water, the bigger one (cylinder P) can hold twice as much as the smaller one (cylinder Q).
So, cylinder P can hold more stuff because it's both taller and a little wider than cylinder Q.
Answer:
7.62 x J
Explanation:
Given:
frequency 'f'= 1.15 x Hz
Planck's constant 'h'= 6.63x Js
Energy of photon can be calculated by the formula:
E= hf
Where,
E= energy of photon
f= frequency of photon
h= Planck's constant
Putting the given values in the formula
E= 6.63x x 1.15 x
E= 7.62 x J
Therefore, the energy of photon is 7.62 x J
Answer:
Explanation:
Given:
Frequency, f = 1.15 × 10^15 Hz
Plancks constant, h = 6.63 × 10^-34 Js
Using the formula,
Energy, E = h × f
Inputting values,
Energy, E = 1.15 × 10^15 × 6.63 × 10^-34
= 7.6245 × 10^-19 J
Energy of the photon , E = 7.6245 × 10^-19 J.
Answer:
12m/s²
Explanation:
Two balls with equal masses and speed engage in a head-on elastic collision. Since the balls of equal mass are moving at equal and opposite speeds, the total linear momentum of the system is zero.
Therefore, the second ball experience an acceleration of 12m/s² at the same time.
Due to the law of conservation of momentum, two balls of equal mass colliding will experience equal but opposite accelerations at the simultaneous point of collision. In this case, if one ball experiences an acceleration of 12m/s^2, the other will experience -12m/s^2.
In the field of physics, this scenario falls under the law of conservation of momentum. According to this law, the total momentum before and after the collision remains the same. If two balls of equal mass collide, and one experiences an acceleration of 12 m/s2, the other ball will experience an equal but opposite acceleration, so -12 m/s2. Please keep in mind, that this is a simplification and real-life situations might be more complex due to factors like friction, air resistance and the angle of collision.
