Answer:
everything will fly about endlessly
Explanation:
the gravitational mass or whatever is now zero, this implies that object that are attracted to each other would no longer gain that attraction due to the absence of the force of attraction putting everything in place

Stan and Silvia Waterson go on a vacation and leave their 17 year old daughter, Jessie, in charge of the house and her two younger siblings. While the elder Watersons are away, a severe storm knocks down power lines and the electricity is off for a week. Since all the food in the refrigerator and freezer spoiled, Jessie talks the owner of a small grocery store into letting her have groceries on credit. When the Waterson parents come back home, the store demands payment from them for the groceries. On what basis must the parents pay for the groceries
Answer:
Generally, minors are not allowed to engage in contracts, except when minors seek basic necessities. Basic necessities include food, shelter and clothes (normal clothes, not designer clothes). If a minor engages in any contract regarding basic necessities, it is considered a valid contract. If a minor engages in contracts to purchase anything else not considered a basic necessity, the contracts are voidable.
How many exercises are there?
Answer:
There are 4 exresise ;endurance, strength, balance, and flexibility. Each one has different benefits.
Explanation:
Endurance activities, often referred to as aerobic, increase your breathing and heart rates.
Your muscular strength can make a big difference. Strong muscles help you stay independent and make everyday activities feel easier, like getting up from a chair, climbing stairs, and carrying groceries.
Balance exercises help prevent falls, a common problem in older adults that can have serious consequences.
Stretching can improve your flexibility. Moving more freely will make it easier for you to reach down to tie your shoes or look over your shoulder when you back your car out of the driveway.

what are laws of newton
Answer:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction
Explanation:
Answer:
Newton's Law of Motion
1- Every object persists in its state of rest or uniform motion - in a straight line unless it is compelled to change that state by forces impressed on it.
2- Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration.
3- For every action, there is an equal and opposite reaction.

a force of 50 n acts on abody of mass 5 kg .calculate the acceleration produced
Answer:
a = 10 m/s²
Explanation:
Given:
Force = F = 50 N
Mass = m = 5 kg
Required:
Acceleration = a = ?
Formula:
F = ma
Solution:
Rearranging the formula for a
=> a = F/m
=> a = 50/5
=> a = 10 m/s²
Dominic made the table below to organize his notes about mixtures.
Properties of Mixtures
has no set composition
must have more than one state of matter
must have more than one substance
What mistake did Dominic make?
The title should read "Properties of Solutions" because some mixtures do not have all of the properties listed.
There is a definite recipe to make each mixture, so the composition of a mixture is set.
Although it is possible to have more than one state, it is also possible to have only one state.
A single substance can be used to make a mixture if the substance is composed of more than one element.
Answer:
Althought it us possible to have more then one state, it's also possible to have only one state of matter
Explanation:
You can make solutions of only one state if matter, for example , it two liquids can be mixed to form a solution they are called miscible.
Answer:
The correct answer is C.) Although it is possible to have more than one state, it is also possible to have only one state.

A 2.2 kW stove burner operates on a 240 V household circuit.
Answer:
I = 9.17 A
Explanation:
We have,
Power of a stove is 2.2 kW
Voltage on which it operates is 240 V
Let us assume that it is required to find the current flowing in the circuit. Electric power is given by :
[tex]P=IV\\\\I=\dfrac{P}{V}\\\\I=\dfrac{2.2\times 10^3}{240}\\\\I=9.17\ A[/tex]
So, the current in the stove burner is 9.17 A.
A train moves at a constant velocity of 50 km/hHow far will it move in 0.5 h?
A. 10 km
B. 45 km
C.25 km
D. 20 km
Answer:
C
Explanation:
[tex]\dfrac{50km}{h}\cdot 0.5h= \\\\\\50km\cdot 0.5=25km[/tex]
Therefore, the correct answer is choice C. Hope this helps!
The correct answer is C.
It is C because .5 h is equal to 30 minutes. So half of 50 km is 25 km(Divided by 2)

The vibrations of a string fixed at both ends are represented by y=16sin(πx/15 )cos(96πt). Where x and y are in cm and t in seconds. Then the phase difference between the points at x=13cm and x=16 in radian
Answer:
Explanation:
y = 16 sinπx/15 cos(96πt)
When t = 0
y = 16 sinπx/15
here πx/15 is phase of the point at x
if x = 13
Phase = 13π/15
if x = 16
Phase = 16π/15
Phase difference
= 16π/15 - 13π/15
= 3π/15
= π/5 radian .

why do we generally hear a thunder when there is a Bolt of lightning
Please answer me fast
Answer:
Explanation:
When a lightning bolt travels from the cloud to the ground it actually opens up a little hole in the air, called a channel. Once then light is gone the air collapses back in and creates a sound wave that we hear as thunder. The reason we see lightning before we hear thunder is because light travels faster than sound!
Answer:
light travels faster than sound

How does a fuse differ from a circuit breaker?
O A. A fuse must be replaced after use, but a circuit breaker can be
reset.
OB. A fuse works by flipping open, while a circuit breaker melts.
O C. A fuse opens the circuit to stop current, but a circuit breaker
closes the circuit.
O D. A fuse works when it detects a high resistance, but a circuit
breaker works when it detects a high voltage.
Answer:
A. A fuse must be replaced after use, but a circuit breaker can be
reset.
Explanation:
A fuse works by actually melting, so there is physical damage that interrupts conduction of current due to lack of conductive material.
The circuit breaker is a switch operated automatically when there is excess flow of current. It interrupts that way the flow of current, but can simply get reset (back to its original close position) once the problem that caused the overflow of current in the circuit is found.
This better agrees with answer A in the list of possible choices.
Determine the following quantities for the circuits shown below:
(a) the equivalent resistance
(b) the total current from the power supply
(c) the current through each resistor
(d) the voltage drop across each resistor and
(e) the power dissipated in each resistor.
WILL MARK AS BRAINLIEST!
Answer:
a) 588.235 ohm ( all the 3 resistors are in parallel )
b) 10 A
c) Current flowing -
in 20 ohm resistor = 6.25 A
in 100 ohm resistor = 1.25 A
in 50 ohm resistor = 2.5 A
d) Voltage drop across all the resistor = 125 V
(As all the resistors are in parallel all the resistors will have the same voltage drop )
e) Power dissipated -
in 20 ohm resistor = 781.25 W
in 100 ohm resistor = 156.25 W
in 50 ohm resistor = 312.5 W
(Power = Current × Potential Difference)

Two wires of circular cross section are made of the same metal. Wire 1 has radius rr and length LL; wire 2 has radius 2r2r and length 2L2L. The potential difference between the ends of the wire is the same for both wires. Find the ratio of the resistance of wire 2 to the resistance of wire 1.
Answer:
Ratio of wire 2 to wire 1 is 0.5 : 1
Explanation:
Wire 1:
length = L
radius = r
Wire 2:
length = 2L
radius = 2r
Resistance of a conductor varies directly as the length and inversely as the cross sectional area. Mathematically
[tex]R = \frac{pl}{a}[/tex]
l = length of conductor
a = cross sectional area of the conductor
p = resistivity of the material with which the conductor is made.
since we are considering the same material, we can ignore the resistivity of the wire.
For wire 1
cross sectional area = [tex]\pi r^{2}[/tex]
therefore,
resistance R = [tex]\frac{L}{\pi r^{2} }[/tex]
For the second wire 2
cross sectional area = [tex]4\pi r^{2}[/tex]
therefore,
resistance R = [tex]\frac{2L}{4\pi r^{2} }[/tex]
Ratio of wire 2 to wire 1 will be
[tex]\frac{2L}{4\pi r^{2} }[/tex] ÷ [tex]\frac{L}{\pi r^{2} }[/tex] = [tex]\frac{2L}{4\pi r^{2} }[/tex] x [tex]\frac{\pi r^{2} }{L}[/tex]
Ratio of resistance of wire 2 to wire 1 = 2/4 = 0.5 : 1
