7. A car is
speeding up
with a force of
a
120 N, heading
East. The
force of
friction acts
against the car
with a force of
80 N West.
What is the net
force?
Answer:Fricition
Explanation: It is fricition in the net force
A car is speeding up with a force of 120 mph and heading east. The force of friction acts against the car with a force of 80 N westward, and the net force acting on the car is 40 N eastward, which means the car is accelerating eastward with a force of 40 N.
What is the calculation of net force?To calculate the net force acting on the car, one needs to consider the direction and magnitude of the forces acting on it. A force of 120 N to the east is acting to accelerate the car in that direction, and a force of 80 N to the west is acting to oppose the motion of the car.
Net force = force of acceleration -force of friction.
Net force = 120 N east- 80 N west.
Net force = 40 N East
Hence, the net force acting on the car is 40 N eastward, which means the car is accelerating eastward with a force of 40 N.

suppose that a white dwarf is gaining mass through accretion in a binary system. what happens if the mass someday reaches the 1.4 solar mass limit?
Answer:
Hey there
When a white dwarf reaches 1.4 solar masses it implodes and becomes a neutron star. this mass limit is known as the "Chandrasekhar limit". It occurs when electron degeneracy pressure (the force that keeps the star from collapsing) is no longer strong enough to hold up aggainsed gravity.

how far from the base of the cliff would the driver have landed if the driver initially had been moving horizontally with speed 10 m/s?
Answer:
C
Explanation:
y0=100 m
y=0
x0=0
x=?
v0x=10 m/s (moving horizontally)
v0y=0
x=x0+v0xt
x=10t
y=y0+1/2at^2
solve for t
0=y0-1/2gt^2
(a is acceleration which is - gravitational acceleration )
t=[tex]\sqrt{\frac{2y0}{g} }[/tex]
plug into x equation
x=10([tex]\sqrt{\frac{2y0}{g} }[/tex]) where y0=100m and g=9.80 m/s^2
x= 45.2 m
if you check the distance when v0=5 m/s, we get x=22.5 m so the equation is correct. however if the g your class uses is 10.00 m/s^2, then we get x=22.4 for the first velocity and 44.7 for the second velocity

A kettle transfers 1,500 J of energy, 1,200 J to a thermal energy store and 300 J to a vibrational energy store (sound). How efficient is the kettle?
Answer:
[tex]\eta = 0.8 = 80\%[/tex]
Explanation:
Efficency of a machine is defined as the ratio of "useful" energy over the total energy imput in it. In this case a kettle wants to heat water, so thermal energy is what we need; if we wanted to build some kind of music instrument, we would be looking at the energy generating vibrations.
[tex]\eta = \frac{1200J}{1500J} = 0.8[/tex]

how much energy is needed to heat 2kg of cooking oil with a specific heat capacity of 2000j/kg°c from 20°c to 120°c
Answer:
400kj
Explanation:
h =mass × specific heat capacity × change in temperature
= 2×2000×[120-20]
=2×2000×100
=400000j
=400kj
400kj of energy is needed.
Energy:Energy, which is observable in the execution of labor as well as in the form of heat and light, is the quantitative quality that is transferred to a body or to a physical system in physics. Energy can be transformed in form but cannot be created or destroyed, according to the rule of conservation of energy. The joule, which is the energy supplied to an object by the labor of moving it a distance of one meter against a force of one newton, is the unit of measurement for energy in the International System of Units (SI).Cooking oil:Cooking oil is a liquid fat made of plants, animals, or synthetic materials that are used in baking, frying, and other cooking processes. It may also be referred to as edible oil because it is used in cold food preparation and flavoring, including salad dressings and bread dips.At room temperature, cooking oil is normally a liquid, although some saturated-fat oils, such as coconut oil, palm oil, and palm kernel oil, are solids.Solution -Formula - h = mass × specific heat capacity × change in temperature
So,
[tex]2[/tex] × [tex]2000[/tex] × [tex][120-20][/tex]
[tex]2[/tex] × [tex]2000[/tex] × [tex]100[/tex]

3. Use the simulation to predict where you think the magnet’s magnetic field was
strongest. Explain your answer.
Magnetic field is stronger at the poles whereas weaker at the center.
The magnetic field on the bar magnet is strongest at the poles because the field lines are most concentrated at the poles while on the other hand, the magnetic field is weaker in the central part of magnet.
Magnetic field has equal amount of strength at both the poles so in my opinion as well as scientific point of view, magnet field is stronger at the poles and weaker at the center of magnet.

A net force of magnitude 0.6 at on a body of mass 40g intially at rest. calculate the magnitude of the resulting acceleration
→ 0.6 N = 0.04 kg × a
→ 0.6 kg.m/s² ÷ 0.04 kg = a
→ 15 m/s² = a
Therefore, tha magnitude of resulting acceleration is 15 m/s².
How much force is needed to accelerate a. 15 kg mass at 20 m/s2.
Answer:
F = 300 N
Explanation:
This is an example of Newton's second Law
F = m * a
F = ?
m = 15 kg
a = 20 m^2
F = 20 * 15
F = 300 Newtons.

Astronomers now think that there is a black hole with more than 4 million times the mass of our Sun at the center of our Galaxy? Roughly how large would the event horizon of such a supermassive black hole be? a. the size of our Moon b. about 4 light years across c. about 17 times the size of the Sun d. about the size of an atom (so much mass really compresses the event horizon) e. we can’t answer this question without knowing exactly what kind of stars were swallowed by the black hole
Given what we know about the astronomical units of space occupied by supermassive black holes, we can confirm that the event horizon in question is roughly 24million km across. Though no option given evaluates to this number, the closest is option c "about 17 times the size of the sun", which equates to the radius of the event horizon.
When comparing sizes, the universe can quickly make even the most massive object appear to be very small. The sun, which is large enough to make the earth look like a speck of dust in comparison, is roughly 700,000 km across. Though this is indeed a massive distance, it is only 1/35th the size of the event horizon in question.
The "Supermassive Black Hole" at the center of our galaxy is known as Saggitarius A. This black hole is said to be 4 million times the mass of our sun. Despite this, however, due to the highly compressed nature of black holes, it is only about 35 times larger than our sun. Option C comes close at 17 times larger but is only about half of what the event horizon for this black hole is.

A 800 Kg car and driver accelerates at a rate of 35 m/s/s. What force is necessary to bring the car to a complete stop?
Answer:
Your answer would be 28,000 N (newtons).
Explanation:
We'd simply get this by using the formula:
force = mass × acceleration
The information that we have from the question is that the force is 800 times 35.
Now, all we have to do is multiply 800 by 35, and we have our answer of 28,000 N.

Calculate the maximum height a ball reaches when thrown straight up at a velocity of 10m/s
Answer:
5.1m
Explanation:
Use the fourth key equation of accelerated motion
vf^2=vi^2+2aΔd
we know vf is = 0 because that is when the ball reaches it's peak (not going up anymore)
0=vi^2+2aΔd
and we can rearrange for Δd, which is what you need
-vi^2=2aΔd
Δd = -vi^2/2a
Now we can plug in the values
Δd = -vi^2/2a
Δd = -(10m/s)^2/2(-9.8)
Δd = -100/-18.6
Δd = 5.10m
