By the end of the war, the allies realized that it would be advantageous to fight the axis forces in multiple locations at the same time.
true or false?

the missing value is the 'k' that should appear between '28' and 'g' .

nobody has a mass of 28g.

my new grandson, who was born yesterday (january 29, 2019), had a mass of 4,039g at birth.  

mother and son are happy and resting comfortably today, in kfar tapuach, samaria, israel.

answer: carrier wave

part a)

when ball will reach to highest point then it's speed will become zero

so we can use kinematics to find the time

part b)

for finding the maximum height we can use another kinematics equation

so it will rise to 1.12 m from the point of projection

part c)

ball will take double the time which it take to reach the top point.

so here the time to reach the top is 2.23 s

so time taken by the ball to reach at same point after projection is given as

since ball have reached to same point so the final velocity must be same as initial velocity

so we have

downwards

part d)

when ball reached to the bottom

displacement of ball = -51.6 m

now by kinematics we have

by solving above equation we have

now for the velocity at that instant we have

so its velocity is 38.6 m/s downwards

part e)

for the position of ball at t = 5.35 s we can use

so it is 23.1 m below the initial position from which it is thrown

now for the velocity we can say

so it will be moving downwards with speed 30.53 m/s

answer

first law of thermodynamics   is an application of law of conservation of energy(according to energy conservation law energy can neither be created nor it can be destroyed only it can transform from one form of energy to another form of energy) which is adapted for thermodynamic systems.

according to first law of thermodynamics heat added to a system is neither created nor destroyed but it can transforms into other forms of energy.
