Answer:
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply one or more plant nutrients essential to the growth of plants. Many sources of fertilizer exist, both natural and industrially produced.
Explanation:
By using the relation between period and frequency, we conclude that the period of the fork is0.0023 seconds.
We know that the relation between period and frequency is:
T = 1/f
where T is the period and f is the frequency.
In this case, we know that the frequency of the fork is 440 Hz, where:
1 Hz = 1/s
Then the period of the fork will be:
T = 1/(440 Hz) = (1/440) s = 0.0023 s
Meaning that each complete vibration of the fork takes 0.0023 seconds.

Answer: alpha decay and beta decay cause the parent nucleus to become a different element.
Explanation:
Alpha decay : It is a radioactive decay in which nucleus emits an alpha particle and turns into different atomic nucleus. During alpha decay, an atom loses 2 protons and 2 neutrons.
Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron.Thus a different element is produced.
Gamma decay : In this process, the unstable nuclei transformed into stable nuclei by releasing gamma rays along with beta or alpha decay.The same element is produced.
together and PROTONS move from one object to the other.
Answer:
true
Explanation:
yes because I said so
B) The magnitude of gravitational forces is greater than the magnitude of electromagnetic forces.
C) The magnitude of electromagnetic forces is always equal to the magnitude of reaction forces.
D) The magnitude of gravitational forces is always equal to the magnitude of electromagnetic forces.
Answer:
The magnitude of electromagnetic forces is greater than the magnitude of gravitational forces.
Explanation:
There are four fundamental forces in nature. These are as follows :
(1) Gravitational force
(2) Electromagnetic force
(3) Weak force
(4) Strong force
Gravitational force is the weakest force among all the fundamental forces. The gravitational force exists between masses present in the universe while the electromagnetic force exist between charged particles. The magnitude of gravitational force is weaker than the electromagnetic force. It is about times more than gravitational force.
Hence, the correct statement about forces in the solar system is (A).
Your image is enlarged.
Your image is reduced.
Your image is real.
Your image is virtual.
All of the above.
Answer:
All are correct
Explanation:
A concave spherical mirror produces both types of images real and virtual of an object.
The concave spherical mirror forms a real image when the object placed between the focus and infinity.
The concave spherical mirror forms a virtual image when the object is placed between focus and the pole of the mirror.
So, it forms real and virtual both types of images and it forms the image size is more than object size, equal to object size and less than the object image.
All the options are correct.
