NOTE: Check your formula sheet if you have one these are often there.
Ac =
= rω^2
We know r = 4.00m
but what is ω?
ω =
= 2π*f
f is our frequency. we want it in seconds so we can divide by 60.
300/60 = 5rev/s
Ac = rω^2 = (4)(5)^2 = 100m/s
(b) Linear speed or v is equal to v = ω = (5)(4) = 20m/s
340 / 20 = 17
The speed of sound is 17 times faster.
NOTE: finished physics so i might be rusty and use an equation wrong. Tell me if something doesnt make sense. Im still new to this myself.
C is the answer because when you go to a Christian school they expect you to have values of that already instilled in you
Answer:
a. longitudinal
Explanation:
A longitudinal study examines a given group over a long period of time, so collecting data from the same group of 30 people over their lifetime certainly fits that definition. It's more like an evolution study.
A cross-sectional compares different groups at the same point in time. So, it's more like a survey.
A microgenetic is much focused in time, providing multiple data sets in a short time to examine rapid evolution of a subject.
An experimental study design will make interactions and experiments with the study group, while this is not the case here apparently, and experimental is usually for a much shorter period than a generation.
Answer:
The three products that the farm can produce and sell are -
a) Honey
b) Milk
c) Egg and Chicken
Two ways of value addition
a) Food processing
b) Packaging and labelling
Explanation:
The three products that the farm can produce and sell are -
a) Honey
b) Milk
c) Egg and Chicken
The two ways by which value can be added to these product is
a) Labelling and packaging - Labelling and packaging the milk, honey and egg can add value to the product and can fetch good some of money
b) Processing the food item - Milk can be processed to produce cheese, curd etc. Price of processed food is much higher than that of non processed food.
The sky is blue because air molecules in the air scatter blue light from the sun more than they scatter red light.
