Answer:

It is a change in velocity over a period of time.

Explanation:

Answer:

6 m/s^{2}

Explanation:

The formula for force is

F = mass x acceleration

F = 12 N

mass = 2 kg

So, you can change the formula to solve for acceleration.

acceleration = F / mass

a = 12 N / 12 kg

a = 6 m/s^{2}

Answer:

The widely accepted theory for the origin and evolution of the universe is the Big Bang model, which states that the universe began as an incredibly hot, dense point roughly 13.7 billion years ago.

Answer:

3 is your anwser

Explanation:

Answer:

It's like the Earth pulling on you and keeping you on the ground. That pull is gravity at work. Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects.

For 9 I think its B but Im not sure

Answer:

the driving gear must be larger than the driven gear

Explanation:

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

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

Explanation:

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].

Answer:

Heat is always the transfer of energy from an object at a higher temperature to an object at a lower temperature.

Explanation:

Answer:

Heat flows from high temperature to low temperature

Explanation:

the answer also may vary it can also be the heat flows from a warmer to colder place

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.

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

Answer:

11.) g = 3.695 m/s^2

12.) g = 8.879 m/s^2

13.) E = 8127 N/C

Explanation:

11.) Given that the

Mercury mass M = 3.3 × 10^23kg

Radius r = 2.44 ×10^6 m

Gravitational constant G = 6.67408 × 10^-11 m3kg-1 s^-2

Gravitational field strength g can be calculated by using the formula below

g = GM/r^2

Substitutes all the parameters into the formula

g = (6.67408 × 10^-11 × 3.3 × 10^23)/(2.44×10^6)^2

g = 2.2×10^13/5.954×10^12

g = 3.695 m/s^2

12.) Given that the

Venus mass M = 4.87×10^24kg

Radius r = 6.05 × 10^6 m

Using the same formula for gravitational field strength g

g = GM/R2

Substitute all the parameters into the formula

g = (6.67408 × 10^-11 × 4.87×10^24)/(6.05×10^6)^2

g = 3.25×10^14/3.66×10^13

g = 8.879 m/s^2

13.) Given that the

Charge = 2.26 nC = 2.26×10^-9

Distance d = 0.05m

Electric field strength E can be calculated by using the formula below

E = Kq/d^2

Where

K = electrostatic constant 8.99 × 10^9 Nm2/C2

Substitutes all the parameters into the formula

E = (8.99 × 10^9 × 2.26×10^-9)/0.05^2

E = 20.3174/2.5×10^-3

E = 8126.96 N/C

Answer: C

Explanation: I dont realy know what this means. but it will not increase because your not getting closer to earths center of gravity and not decreasing because your not high enough in the atmosphere.

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.
