A675 g air-track glider attached to a spring with spring constant 9.50 n/m is sitting at rest on a frictionless air track. a 600 g glider is pushed toward it from the far end of the track at a speed of 160 cm/s . it collides with and sticks to the 675 g glider. what are the amplitude and period of the subsequent oscillations?

To solve this problem we will proceed to find the period given by the spring, said period must be calculated considering the totality of the masses. At the same time, we will also calculate the final velocity resulting from the impact. With speed and period it will be possible to finally find the amplitude.

The period is defined as,

Here,

m = mass

k = Spring constant

According to conservation of momentum

Initital momentum = Final momentum

Now the amplitude of oscillation is

Here,

v = Velocity

A = Amplitud

T= Period

Therefore the ampliude is 0.275m and the Period is 2.301 of the subsequent oscillations.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
