Imagine a third particle, which we will call a cyberon. It has three times the mass of an electron (3m3m). It has a positive charge that is three times the magnitude (3qe3qe) of the charge on an electron. What is the ratio of the speed vcvcv_c that the cyberon would have when it reaches the upper plate after being released from rest at position h0h0h_0 to the speed vevev_e that the electron would have? That is, what is vcvevcve?

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

b.a device that inputs heat into a cool object

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
