<span>The moon is smaller and more dense than the Earth, and has less extreme temperature changes. The statement presented is True. In terms of temperature, since there is no atmosphere on the moon, then it has less extreme temperature changes. The moon can reach 253 Fahrenheit in the day and -387 Fahrenheit at night.</span>
Answer: A, C, E
Explanation:
Gamma rays, Microwaves, and Radio waves
Explanation:
KE = 1/2*m*v^2
mass won't change
but velocity is
A: the force is pushing against the direction of the object, so velocity is decreasing, so KE is decreasing
B: the F net line is pretty much straight up, which means there is no net force pushing to the left, but velocity is still increasing
Why? Because if you use the pythagorean theorem, the hypotenuse is always longer than the legs.
Note: velocity only ever stays the same if there is no net force (or 0 acceleration), so all four of these are either decreasing or increasing
C: there is a net force to the right, so velocity is increasing
D: There is a net force to the right but velocity is to the left, so velocity is decreasing
Hope I got these right
Strong nuclear force is most like electrical force because they are both related to distance statement best describes the similarities between fundamental forces.
<u>Option: D</u>
<u>Explanation:</u>
There are four forms of fundamental forces in nature. They are called gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force. Strong nuclear force is a spin-dependent, charging-independent force that arises into being due to the mutual association of gluons binding protons and neutrons.
It is also hundred times more powerful than electromagnetic force. Poor nuclear capability comes into being during radio-active decay. This force is due to the interaction of 'w' and 'z' bosons (particles such as protons and neutrons with integral or zero spin) that are heavier in nature. The function of this force is to turn protons into neutrons and vice versa.
Answer:
a)F=(208 i+156 j) kN
b)F+W=219 kN
Explanation:
Solution:
To determine the components of F
F=(260 kN).(
)
=(208 i+156 j) kN
F=(208 i+156 j) kN
b)weight W expressed in component and add into the
Force F.
W=-(8800 kg).(9.81 m/s^2)j
F+W=(208 i+[156-86.3]j) kN
F+W=
=219 kN
F+W=219 kN
