Answer:
%Open the file.
fID = fopen('parts_inv.dat');
%Read from the file.
data = fscanf(fID,'%d\t%f\t%d',[3,inf]);
%Close
fclose(fID);
%Restore the data.
data = data';
%Get the size
[rs, cs] = size(data);
%Set value.
invCost = 0;
%Loop
for rw = 1 : rs
%Find cost
invCost = invCost + (data(rw, 2) * data(rw, 3));
%Loop end
end
%Display the cost.
fprintf('Total cost: %4.2f\n\n', invCost);
Explanation:
Based on how they each acted in the trials, the substance that would be the most metallic is B.
Answer:
it will decrease
Explanation:
According to the law of universal gravitation, the gravitational force exerted by the moon on the spacecraft is equal to the product of their masses and inversely proportional to the square of the distance that separates them. Therefore, as the spacecraft moves away, its distance increases and the force of attraction exerted by the moon decreases.
Answer:
2a.
a=1.13ms^-2
2b.
S=277m
2c.
V=27.7ms-¹
Explanation:
Initial Velocity (U)=22m/s¹
Final Velocity (V)=43m/s²
Time(t) =18.6s
a. a=V-U/t
a=43-22/18.6
a=1.129
a=1.13m/s²
2b.
S=ut+1/2 at²
s=22(10)+1/2×1.13(10)²
s= 220+0.57(10)²
s= 220+0.57(100)
s= 220+57
s=277m
2c.
V=U+AT
V=22+1.13(5)
V=22+5.65
V=22+5.7
V=27.7m/s¹
There is 1 Mg and 2 Cl i think
