A rectangular concrete slab is 0.80m long, 0.60m wide, and 0.05m thick A- calculate its volume in m'2
B- the mass of the concrete slab is 60 kg. Calculate its density in kg/m'2

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50
