Numerical: a) A body of mass 50kg is moving in a forward direction when a force of 10N is applied on it. Calculate
the acceleration produced in the body

Explanation:

Given:

Force = F = 10 N

Mass = m = 50 kg

Required:

Acceleration = a = ?

Formula:

F = ma

Solution:

For a, the formula will be:

=> a = F/m

=> a = 10/50

=> a = 0.2 m/s²

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
