Answer:
The answer is %pearlite = 0.06%
Explanation:
according to the exercise we have that the percentage is 1.88% C, therefore, the percentage of perlite is equal to:
%pearlite = (B*C)/(A*C) = (2-1.88)/(2-0) = 0.06%
The percentage of cementite is equal to:
%cementite = (1.88-0)/(2-0) = 0.94%
Answer:
The ground pushes back on your feet with equal force.
Explanation:
Newton's Laws of Motion
In order to find the efficiency first we will find the Change in Potential energy of the small stone that robot picked up
First we will find the mass of the stone
As it is given that stone is spherical in shape so first we will find its volume
Now it is given that it's specific gravity is 10.8
So density of rock is
mass of the stone will be
now change in potential energy is given as
here
g = gravity on planet = 0.278 m/s^2
H = height lifted upwards = 15 cm
Now energy supplied by internal circuit of robot is given by
V = voltage supplied = 10 V
i = current = 1.83 mA
t = time = 12 s
Now efficiency is defined as the ratio of output work with given amount of energy used
so efficiency will be 23 %
The advantage is that we do not run out of resources and a disadvantage is that is dangerous when a “human” gets too close and gets sick by the radiation.
