The dimension of a/b where x is the distance and t is the time is T
Given the expression
x = at + bt²
where
x is the distance
t is the time
Based on the homogeneity principle, the expression on the left-hand side must be equal to that on the right. Hence;
x = at
Since x is the distance and distance is measured in metres, the dimension equivalent will be the length 'L'
Since t is the time and time is measured in seconds, the dimension equivalent will be the seconds 'T'
Similarly;
x = bt²
Next is to get a/b;
Hence the dimension of a/b is T
40% of the Earth's surface is covered by continental crust.
For us to understand the missing item that would complete beta decay reaction, we need to achieve in depth understanding of chemical formulas and nuclear symbols. Next is to have great comprehension of the following points:
<span>1.) Neutron in nucleus breaks down and changes into a proton.
2) Then it emits an electron, as well as an anti-neutrino which go into space.
3) Lastly, atomic number continuously goes UP while mass number remains unchanged.</span>
Answer:
A. Mass
Explanation:
Inertia is the resistance of an object to any change in its velocity. Inertia depends only on the mass of the object: the greater the mass, the larger the inertia of the object, because it will be more difficult to change the velocity of the object.
An example to better understand: assume there is a golf ball rolling with a certain speed, and a car moving with the same speed. If we want to stop the two objects, we will need a much larger force for the car, because its mass is much greater than the gold ball, so it has much more inertia than the golf ball.
Answer:
A
. It will allow vertically polarized light to pass through it.
Explanation:
Polarization is the attribute in which waves oscillate in a particular direction relative to the direction of travel. The direction of polarization determines the type of polarized light produced. Since the chemical molecules are vertically aligned, it will only allow vertically polarized light pass through it.
