If the position vector of the particle is given by vector r=3t^2i+5tj+4k find the velocity of the particle at t=3secs
speed of the particle at t=3secs
acceleration of the particle at time t=3secs​

double the distance = divide strength by 4

vapour or gas assuming atmospheriv pressure

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
