The baseball because it has a greater mass and would go farther because it don't have holes for the air to go through and slow it down
Answer:
Biodiesel is considered a renewable energy source because it is made with animal fat
Explanation:
Biodiesel is a fuel generated from animal fats, vegetable fats, using a catalyst for chemical formulation of biodisel.
It is a renewable source of fuel, as it can be replenished (renewed) easily & in shorter time, since it is made of animal fats & vegetable fats. Unlike non renewable fuels which take long periods to replenish (renew), like fossil fuels.
So, Biodiesel is considered a renewable energy source because it is made with animal fat
Answer:
Slowing down: A car decelerating because it's coming up to a red light.
Speeding up: A car accelerating because a red light has turned to a green light.
Moving at a constant speed, but changing direction: A car turning at a curve.
Moving at a constant velocity, with zero acceleration: A car on an empty highway.
Explanation:
Drive a car around or look at cars on the highway, you'll see the examples listed above happening all the time.
Answer:
axial V = 0
equatorial V = k q 2a / (x² -a²), V = k q 2x / (a² -x²)
Explanation:
A dipole is a system formed by two charges of equal magnitude, but different sign, separated by a distance 2a; let's look for the electrical potential in an axial line
V = k (q / √(a² + y²) - q /√ (a² + y²))
V = 0
the potential on the equator
we place the positive charge to the left and perform the calculation for a point outside the dipole
V = k (q / (x-a) - q / (x + a))
V = k q 2a / (x² -a²)
we perform the calculation for a point between the dipo charges
V = k (q / (a-x) - q / (a + x))
V = k q 2x / (a² -x²)
Answer:
L = 0.475 m = 475 mm = 18.7 inches
Explanation:
A cylindrical specimen of a nickel alloy having an elastic modulus of 207 GPa and an original diameter of 10.2 mm (0.40 in.) will experience only elastic deformation when a tensile load of 8900 N (2000 lb ) is applied. Compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in).
E = 207 GPa = 207*10⁹ Pa
D = 10.2 mm = 0.0102 m
P = 8900 N
ΔL = 0.25 mm = 2.5*10⁻⁴ m
L = ?
We can use the Equation of the Hooke's Law
ΔL = P*L / (A*E) ⇒ L = ΔL*A*E / P
⇒ L = (2.5*10⁻⁴ m)*(π*(0.0102 m)²*0.25)*(207*10⁹ Pa) / (8900 N)
⇒ L = 0.475 m = 475 mm = 18.7 inches
