Answer:
To find the acceleration of the object we have to apply Newton second law of motion that is F = mass × acceleration.
Explanation:
Given ,
F = 130N
M = 24kg
A = ?
F = m× a
then ,
130N = 24kg ×a
a = 130/24 = 5 m/s.
Answer:
yes, radio waves and x-rays are type of light.
Answer:
(a) has the highest frequency
Explanation:
E = hf...where E(is the energy of a photon);h(is the planck's constant) and f is the frequency of the photon
Whereby this formula shows us that energy of a photon is directly proportional to its frequency
So hence if the energy is high then the frequency of the photon is also high
Gravity constantly acts on the apple so it goes faster and faster ... in other words it accelerates.
Ignoring air resistance, its velocity increases by 9.8 meters per second every second. That is two lots of "per second" and is written:
9.8 m/s2
9.8 m/s2 is the acceleration due to gravity near the Earth's surface. Nearly everything in our lives happens near the Earth's surface, so that value gets used a lot, and is written as a little g:
g = 9.8 m/s2
The average value of g is 9.80665 m/s2, but values are different around the world, such as Calcutta at 9.78548, London at 9.81599 and Tokyo at 9.79805.
So most people just use 9.8 m/s2
Answer:
D
Explanation:
On an inclination of 30°, the acceleration down the inclination will be gsinФ. So the acceleration will be ⇒
g Sin30° = (0.50) g
