Answer:
M = 3.485 kg
m = 1.605 kg
Explanation:
F = 0.98 x 10^-8 N
r = 19.5 cm = 0.195 m
M + m = 5.09 kg ...... (1)
By use of Newton's gravitational law
F = G m1 m2 / r^2
0.98 x 10^-8 = 6.67 x 10^-11 x M x m / (0.195)^2
M x m = 5.59
M - m = 1.88 .........(2)
By solving the equation (1) and equation (20, we get
M = 3.485 kg
m = 1.605 kg
Answer:
False
Explanation:
Heat capacity;
The ability of absorbing the heat is know as heat capacity of the substance.In other words we can say that the ability to retain the heat without changing its temperature is known as heat capacity.
The specific heat of water (liquid) is 4.1813 KJ/kgK andf the specific heat of ammonia (liquid) is 4.7 KJ/kgK.
So we can say that the above given statement is False.
Therefore answer is --
False
Answer:
-4/7
Explanation:
Given the following
A=4i-10j and B= 7i+5j
A+ bB = 4i-10j + (7i+5j)b
A+ bB = 4i-10j + 7ib+5jb
A+ bB =
The vector along the x-axis is expressed as i + 0j
If the vector A+ bB is pointing in the direction of the x-axis then;
Hence the value of b is -4/7
