What is the mass of an object that has a weight of 80.0 N?
Answers
Explanation:
SUPONIENDO QUE LA ACELERACIÓN DE LA GRAVEDAD ES [tex]9.80 m/s^{2}[/tex]
USANDO LA SEGUNDA LEY DE NEWTON:
m = 80.0 N/[tex]9.80 m/s^{2}[/tex] = 8.16 kg
Answer:
8kg
Explanation:
using the formula Force(F)=mass(m)×acceleration(a),
since we are finding the mass of the object,we will make m the subject by dividing both sides by a.
you will now get m= f/a
the acceleration on Earth is usually 10m/s
m= 80/10
m= 8/1 which is also 8kg

A negative slope on the velocity vs. time graph indicates that the object is not
accelerating
A. True
B. False
Answers
Answer: False, I think
Explanation:
Well it depends. Its hard to say without a function of the graph. Given a velocity graph, the first derivative is the acceleration.
Negative slope on a velocity graph means you are going in the negative direction. And over time, your velocity per unit of time is also decreasing. That means we are accelerating in the negative direction

A golfer is teeing off on a 130.0 m long par 3 hole. The ball leaves with a velocity of 35.0 m/s at 35.0° to the horizontal. Assuming
that she hits the ball on a direct path to the hole, how far from the hole will the ball land (no bounces or rolls)?
Answers
Answer:
The ball will land 12.5m before that hole.
Explanation:
The motion of the golf ball can be considered as a projectile motion, where first its height is 0, then it keeps increasing to a maximum point, after which its height starts decreasing again and hits the ground (height becomes 0 again).
We need to calculate the Range (horizontal distance) of the ball which is given as:
[tex]R=\frac{v_i^2{\cdot}sin2\theta}{g}[/tex]
Where
v(i) = initial velocity = 35 m/s
θ = Initial angle = 35°
g = gravitational acceleration = 9.8 m/s
Substitute in the given formula to find Range:
[tex]R=\frac{(35)^2\cdot{sin}(2)(35)}{9.8}\\R=\frac{(1225)(0.94)}{9.8}\\R = 117.5~m[/tex]
Distance between the hole and position where ball lands = 130m - 117.5m = 12.5m

Calculate the wavelength of an electron mass 9.1*10^-31kg moving with a velocity of 2.0*10^6m/s (h=6.63*10^-34Js) (Hint: De Broglie's wavelength)
Answers
Answer:
Wavelength, [tex]\lambda=3.64\times 10^{-10}\ m[/tex]
Explanation:
We have,
Velocity an electron is [tex]2\times 10^6\ m/s[/tex]
Mass of an electron is [tex]9.1\times 10^{-31}\ kg[/tex]
It is required to find the wavelength of electron. The De-Broglie wavelength of an electron is given by :
[tex]\lambda=\dfrac{h}{mv}[/tex]
h is Planck's constant
[tex]\lambda=\dfrac{6.63\times 10^{-34}}{9.1\times 10^{-31}\times 2\times 10^6}\\\\\lambda=3.64\times 10^{-10}\ m[/tex]
So, the wavelength of an electron is [tex]3.64\times 10^{-10}\ m[/tex].
How does the value of the electrostatic force vary with the value (how many) of the charges?
Answers
Answer:
Electrostatic force is directly proportional to the amount of charge on each body under consideration.
Electrostatic force increases with increase in charge.
Electrostatic force decreases with decrease in charge.
Explanation:
Electrostatic force is the force between 2 charges which can be explained by the Coulomb's Law:
F= K (q₁)(q₂)/r²
Where
F= Electrostatic Force
K = Constant of Proportionality
(q₁) and (q₂) = Amount of charge on each body
r = Distance between two bodies carrying charge
If the value of (q₁) or (q₂) is increased considering the other factors remain constant, the value of F will also increase.
And vice versa.

If the billing cycle length for a credit card is one calendar month, which of the
following months will result in the greatest periodic interest rate?
O A. December
B. June
C. April
!!!2O D. September
Answers
Answer: A.) December
Explanation:
December has the highest number of days in the options given above, with 31 days compared to the others with 30 days within a calendar month. The billing cycle is used to refer to a time interval between the end and the next billing or statement date. In the scenario above, the billing cycle length is monthly, meaning the periodic interest will be paid over a 31 day span time before thre beginning of another cycle.
For example, if periodic interest is $1 per day, this amount totals ($1 × 31) in december compared to the ($1 × 30) Interest in the June, April and September billing cycle.

B. The system is the stove, pot, and water.
C. The system is the building containing the stove.
D. The system is the entire Universe.
Answers
Answer:
A. The system is the pot and water.
Explanation:
Thermodynamics is an aspect in science which deals with the applications of heat energy. The useful applications of heat energy to perform work.
In the given question, the pot and water is the system which both absorbs heat energy from the stove. Thus, the system is a closed system since it shares heat energy with its surroundings.
The surrounding of the system extends from the boundary of the pot to the universe.

a car travels 60 km in 2 hours 84 km the next 1 hour and then 68 km in 8.9 hours before reaching its destination what was the cars average speed in km / h
Answers
Answer:
17.8 km/hr
Explanation:
Average speed = distance / time
The total distance traveled is 60 km + 84 km + 68 km = 212 km.
The total time is 2 hr + 1 hr + 8.9 hr = 11.9 hr.
The average speed is 212 km / 11.9 hr = 17.8 km/hr

The throwback PFD is which type?
Answers
Answer:a
Explanation:
The throwback PFD is a Type III PFD. This type of PFD is designed for calm, inland water, or where there is a good chance of quick rescue. THe correct option is C.
Type III PFDs will not turn unconscious wearers to a face-up position, so the wearer may have to tilt their head back to avoid turning face down.
Type III PFDs have the same minimum buoyancy as Type II PFD. Float coats, fishing vests, and vests designed for various water sports are examples of Type III PFDs. Some Type III PFDs are designed to be inflated upon entering the water.
Offshore life jackets of Type I are suited for all areas, notably open, choppy, or isolated regions where rescue may be delayed and offer the highest buoyancy. Near-shore vests of Type II PFDs are designed for calm inland water or situations where there is a good probability of prompt rescue. Throwable PFDs of Type IV are suitable for usage in open water as well as calm, heavily used inland waters where assistance is always available. Special-purpose PFDs known as Type Vs are made for activities like kayaking and whitewater rafting.
The throwback PFD is not a Type I PFD because it does not provide the most buoyancy and is not designed for all waters. It is not a Type II PFD because it is not intended for calm, inland water or where there is a good chance of quick rescue. It is not a Type IV PFD because it is not intended for calm, inland water with heavy boat traffic, where help is always present. It is not a Type V PFD because it is not designed for specific activities such as kayaking or whitewater rafting.
Therefore, the correct option is C. type III.

A ball rolls with a speed of 4.0 m/s across a level table that is 1.0 m above the floor. Upon reaching the edge of the table, it
follows a parabolic path to the floor. How many meters along the floor is the landing spot from the table?
Answers
Answer: 1.81m
Explanation:
Given the following:
Horizontal speed = 4m/s
Height of table = 1m
Taking the vertical component of the motion:
Using:
S = ut + 0.5 at^2
Where, S = height of table, a = acceleration due to gravity (9.8m/s^2), t = time and u = Initial Velocity in vertical direction = 0
1 = 0(t) + 0.5(9.8)t^2
1 = 4.9t^2
t^2 = 1 / 4.9
t^2 = 0.204081
t = sqrt(0.204081)
t = 0.452s
For Horizontal :
Gravitational acceleration is absent, therefore distance can be calculated using:
Distance = Velocity × time
Distance = 4m/s × 0.452s
Distance = 1.808 m
Distance = 1.81m
