Answer:
Isotopes
Explanation:
Atoms of the same element always have the same number of protons. But, Atoms of the same element can have a different number of neutrons.<em> We call these isotopes.</em> These 3 examples of uranium have the same amount of protons within them but a different number of neutrons, hence the change in atomic mass.
The airplane's speed relative to the ground is
√ (100² + 25²)
= √ (10,000 + 625)
= √ 10,625
= 103.08 km/hr .
The angle of its velocity north of west is
the angle whose tangent is (25/100)
arctan(25/100) = 14° north of west .
(bearing = 284°)
Answer:1.89 m
Explanation:
Given
Block travels in first second
It is released from rest i.e. initial speed is zero (u=0)
using
where a=acceleration
here acceleration is the component of gravity on incline plane (say )
so
So distance traveled in
So distance traveled in is
