b The area of the rectangle represents the displacement if the object had moved at a steady speed u for time t. You may need to find the value of a trigonometric function (such as sine or cosine) of an angle whose value is given in radians. ii State whether the frequency of the vibrator must be increased or decreased to form the same stationary wave pattern on the string as shown in the diagram. This is an exercise in understanding and using the equation for calculating gravitational potential.
Exam-style questions TIP Be careful not to confuse questions on the double-slit experiment and on the diffraction grating. m. a Calculate the gravitational force on a mass of exactly 1 kg on the surface of the Moon (gravitational constant G = 6.
It accelerates but eventually reaches a constant velocity downwards, known as the terminal velocity. State the difference between the direction of electron flow in a circuit and the direction of the conventional current. Diffraction and the diffraction grating This exercise helps you understand the role of diffraction and gives you practice in using the diffraction grating formula.
b Now, following the same procedure as in question 3, make a scale drawing and use it to deduce the magnitude and direction of the resultant force on the ship. b In the reaction, the total rest mass of the products is smaller than the mass of the 30 P 15 nucleus. Detailed Learning support is provided throughout to help students to tackle the different exercises and build confidence to answer questions independently. Remember that ‘decelerating’ means that the car’s velocity is decreasing; its acceleration is negative.Helps students understand what is required in an exam and develop the skills needed to be effective in an exam situation. To obtain satisfactory measurements of the extension of the wire, it should be several metres in length. State whether the collisions between the particle and the walls of the cube are elastic or inelastic.
Copy the diagram and, using the same axes: a Sketch the variation with time of a wave with twice the amplitude; your wave should be in phase with the wave in the diagram. Air resistance acts in the opposite direction to the ball’s velocity and increases as its velocity increases.
This exercise will give you practice in calculating electrical forces, work done and electric potential. Cambridge International AS and A Level Business Coursebook with CD-ROM (Cambridge International Examinations) [3 ed. a Choose a suitable section of the graph and deduce by how much the block’s temperature increased in 200 s. Her proof is: Vt = V1 + V2 IRt = IR1 + IR2 So, Rt = R1 + R2 a State where Kirchhoff ’s first law is used in the proof. Draw a diagram to show how these two velocities add together to give the resultant velocity of the aircraft.
e Is the true value for the specific heat capacity of copper likely to be higher or lower than that calculated in part c? Stretching things When considering the effect of tensile forces on a spring, we need only consider the load and extension. State which of these two types of thermometer shows a big change in resistance over a small change in temperature. e Suggest why having lines as far apart as this for a diffraction grating experiment is not suitable. Explain why this means that a thermocouple thermometer is likely to respond more quickly to a change in temperature.
On your diagram add an arrow to show the direction of this force at the point where α-particle 3 is closest to the nucleus.
