Answer:
(a) A+B = 2i-3j
(B) A-B = 4i + j
Explanation:
We have given two vectors A = 3i-j and B = -1-2j
We have to find the two vectors that is A+B and A-B
(A) In first art we have calculate A+B for this we have to add simply vector A and v ector B
So A+B = 3i-j-i-2j = 2i-3j
(B) In this part we have to find A-B for this we have to simply subtract B from A so A-B = 3i-j-(-i-2j) =3i-j+i+2j =4i+j
An example helps clarify the difference between an analysis, a deter- mination and ... departments analyze samples of water to determine the concentration of ... moles of Cu2+, and cylinder 2 contains 20 mL, or 2.0 × 10.
Answer:
9064.44 Nm
Explanation:
Since the steel is uniform, the center of mass is also at the geometric center, which is 3.5 / 2 = 1.75 m from the bolted point.
Let g = 9.81 m/s2. The weight of the beam and the worker is
So the total torque about the bolted point is the sum of product of weights and distances from weight to the bolted point
Earth is more suitable because it has an atmosphere that is suitable for life, Earth has fresh water, and it is the safest distance from the sun. Plants increase the viability of life by producing Oxygen for animals and using carbon dioxide for photosynthesis. Volcanoes are present because of the pressure built up in the core of these planets. The inner planets are small in size compared to the outer planets. The temperature is much hotter and they are solid structures. Beyond Mars, these planets are gases and are much larger. There are many pictures and telescopes that explore the universe and show evidence of planets outside of the solar system.
