Two charged objects have a repulsive force of 0.040 N. If the distance separating the objects is doubled, then what is the new force?
Answer:
Force will be 1/4 of the original
Explanation:
F = G m1 m2 / d^2 now change the distance to 2d
F = Gm1m2 / (2d)^2
F = 1/4 G m1 m2 / d^2 the force is reduced to 1/4 of the original

Explanation:
Paula ran a total of 72meters directly toward school at a constant velocity. She ran one-third of that distance in 8seconds. What was her velocity?
Answer:
3 meters per second
Explanation:
72 divided by 3= 24 meters in 8 seconds
24/8= 3, so 3 meters per second
Velocity can be described as the same thing as speed but with _________________ included
Answer:
Direction
Explanation: Hope this helps!
Answer:
nvm its direction :))
Explanation:
Speed and velocity both represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity are measured in the same units: meters per second or m/s.
Velocity is a measure of both speed and direction of motion. Velocity is a vector, which is a measurement that includes both size and direction. Velocity can be represented by an arrow, with the length of the arrow representing speed and the way the arrow points representing direction.

A car traveling at 35m/s appliance its brakes 10 seconds later it has a velocity of 5m/s what is the acceleration of the car
Answer:
a = -3 m/s^2
Explanation:
Vi = 35 m/s
Vf = 5 m/s
t = 10 s
Plug those values into the following equation:
Vf = Vi + at
5 = 35 + 10a
---> a = -3 m/s^2

A circle graph shows that one-fourth of the students in a particular school ride the bus every day. What is this equivalent measurement in radians? In degrees?
Answer:
it's 1.57... radians and 90°
As par circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.
What is circle graph?Pie charts are another name for circle graphs. The graph is shaped like a circle, with many wedges that each represent a portion of the overall.
The circle graph is commonly referred to as a pie chart since these wedges frequently resemble pie slices. The circle graph's angles are proportionate to the quantity they each represent.
According to circle graph:
Total number of student in the particular school = 2π radian.
So, one-fourth of total number of student in the particular school = 2π/4 radian
= π/2 radian.
Hence, according to circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.

What is the mass of a sample of glass ( specific heat - 0.50J/kg*"C), if it requires 490 J of heat to raise the temperature from 18.0°C to 0.0°C?
Answer:
Q=mc∆tita.
490J= m× 0.5J/Kg/C × (18-0°C)
490J= m × 9J/kg
490J
9J/Kg = m.
m= 54.4Kg

Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 5.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle?
Answer:
Particle A: K.E = 38.3 J
Particle B: K.E = 7.67 J
Explanation:
Given that Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 5.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle?
The total kinetic energy of Particle A and particle B should be equal to 46 J
Since the mass of A is 5.00 times the mass of B, then, the K.E energy of each particle can be calculated by using ratio.
5 + 1 = 6
K.E for particle A
5 /6 × 46 = 230 / 6 = 38.3 J
K.E for particle B
1/6 × 46 = 46 / 6 = 7.67 J

how many grams are in 3 moles of helium?
Answer:
12 g
Explanation:
No of moles = [tex]\frac{mass}{mass.in.1.mole}[/tex]
But we have to find the mass, not the number of moles. So,
Mass = No. of moles × mass in 1 mole
Mass of helium = 4
Mass = 3 × 4
= 12 grams

Tarzan is swinging back and forth
on a 6.25 m long vine. What is the
period of his oscillation?
(Unit = s)
Answer:
5.02s
Explanation:
I got it right in acellus :)
The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.
Calculation of the period:Since
Length L = 6.25 m
g = 9.8 m/s²
So,
T = 2π√(L/g)
T = 2π√(6.25 / 9.8)
T = 5.01 sec
Hence, The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.
