If Earth were farther from the sun, which change would be more likely to occur?

In a region of space there is a uniform magnetic field of magnitude 0.25mT pointing vertically straight down.

A bullet of mass 10.0 g is fired into the block and embeds in the block. The block rises a height of h = 5.00 cm. (a) Draw a figure showing the initial and final positions of the block. (b) What was the speed of the bullet? (c) How much thermal energy is generated in the block? (d) If the bullet stops in a distance of 4.00 cm inside the block, estimate the force of friction. SOLUTION : (b) The problem consists of two stages. The first stage is from before to after the impact. The second stage is from just after the impact to the final position. In the first stage, the linear momentum is conserved. In the second stage, the energy is conserved. Let us denote the initial speed of the bullet as v0 . So: pbefore = pafter mv0 = (m + M ) v (4) M +m v0 m M y=0 Then using the conservation of energy of the combined mass rising to height h after the impact: 1 (M + m) v 2 = (M + m) gh 2 ⇒ v = 2gh (a)

For the first part, the principle of conservation of energy is investigated by launching a ball vertically and comparing its total energy at the time of launch to its energy when it reaches its highest point. For the second part, the principle of conservation of energy is tested out for an isolated system by investigating how gravitational potential energy is transferred to kinetic energy for a glider (of mass m) sliding on an air

1. Step 1: Identify the problem. If a hole is cut into an iron plate and the plate is heated in an oven, will the hole get bigger or smaller?

Step 6: The golf ball that rolls of the ledge falls onto the meter stick flipping a pan of pie up which was our main goal. We had to make sire and measure if the golf ball would hit the meter stick. The golf ball would have to be in Kinetic motion so it could move. The speed of the ball didn't matter. The energy was transformed into the meter stick from the golf ball. The energy then throw up the pie. With the mass of the ball we could have a nof force to flip the

If new entrants to your industry are forced to come in on a large scale and face retaliation from existing firms, this raises barriers to entry. If new firms must spend heavily up front to build a brand name, this investment is significant and discourages entry. If the use of anew company’s product requires potential users to make massive changes in their business – large investments in new equipment, extensive retraining, complete product redesign, etc., this discourages entry. High up-front costs such as advertising, research, or capital equipment will discourage entry. If the stakes are very high, entrance is limited to a few large companies having deep pockets. If distribution is limited, competition can be fierce for shelf space, etc. New entrants may have to offer price breaks and allowances to break in, or be willing to create new distribution channels. New entrants who lack experience must expect high unit costs until the firm becomes more efficient. Policy and economic treaties may influence a company’s ability to enter the market.

Motion and Energy are both related and understanding of both are important in the completion of this experiment. There are four main equations of motion, Vav = s/t, v = u + at, v2 = u2 + 2as & s = ut + ½at2. These four equations can be used to determine the information of an objects motion (Henderson n.d. a). There are different types of motion, specifically for

The first thing that needs to be described in this lab is what the electric current I:

From the equation it can be said that the energy emitted has a relationship with planck’s constant and the frequency of emitted radiation.

4. It is because the pivot point is on the center of the mass of the rule. The mass is cancelled off as the lever distance is 0.

First and foremost I am extremely discouraged about the grade I have in your class right now as it does not reflect at all what I have put in. Starting from the beginning of the year, I understand what I did wrong on the Engineering Presentation. Where I am a little disappointed is where for example, on the 4.2 Linear Motion homework, you gave me a C+ and out of the whole assignment you only crossed out the word "usually". Also, on the 4.2.2 Projectile Motion homework, you gave me an F because I read one of the questions wrong even though I had written the correct answer on the paper and I wrote down for the third question 1) Initial Velocity, 2) Firing Angle which I understand why it was unnecessary to put it down, and 3) Gravity. For these 2 minuscule mistakes on this sheet, I do not think it is an F quality homework. I have both of these sheets still on file and will take a picture of them for your review because I truly feel like those should be changed but that is up to you in the end. In regards to the Ballistics Quiz, I do not know what went wrong as I did very well with the classwork you assigned but there is nothing I could do about that now.

The subject of physics applies calculus to many of its principles in order to explain various concepts and objects. In my HL math class, I have used calculus, such as differentiation and optimization, and applied it to kinematics (displacement, velocity, acceleration), which I started learning in my SL physics class. While looking for a topic for the exploration, I thought of pursuing this connection between calculus and physics, and discovered that calculus was present heavily in physics, even more than I had previously thought. While a lot of concepts used simple differentiation and derivatives, I found out that the concepts of work, forces, and energy used the more complex math of integration in order to explain them.
