ISTO Senior Sample Paper
1.During a hurricane, winds can blow out windows and walls, or remove the roof from a house. According to Bernoulli’s principle, which of the following statements best explains why this can occur?
A.Wind blowing around and over a house creates convection currents outside the house.
B.Wind blowing around and over a house is at a lower pressure than the air inside the house.
C.Wind blowing around and over a house is at a higher temperature than the air inside the house.
D.Wind blowing around and over a house creates electrostatic charges in the air around the house.
2.Clark took a comb by which he combed his hair and the comb got statically charged and brought it near to the flow of water from the water tap after which the flow of water got deflected, what could be the best explanation from the following options for the same situation?
A.Because water contains polar molecules in it.
B.Because of the dissolved ions present in water.
C.Because of magnetic property that is present in water
D.Water is not deflected at all, it’s attracted.
3.In many microwave ovens, a turntable slowly rotates food while the oven is in operation. The turntable, however, was not part of the original microwave oven design. Which of the following statements is the most likely reason the turntable was added to the microwave oven?
A.Food did not cook evenly.
B.The oven used too much power.
C.Food did not receive enough energy.
D. The oven became too hot during operation.
4.Accelerometer is also used in laptops, what could be reason to use accelerometer in laptops?
A.To rotate the screen
B.To protect hard drives from damage
C.To get the angle on monitor
D.To get the linear acceleration
5.Mohit made a 3-axis solar tracker where it will track sun’s position accordingly, he has used servo motors in all the axis for the movement. What could be the reason behind to choose servo motor as he could also have used stepper motor?
A.Servo motor have good inbuilt quality than the stepper motor.
B.Servo motor is more efficient than stepper motor.
C.Servo gives dynamic adjustment and stepper motor is start and stop motor.
D.Servo motor consumes less energy than stepper motor.
6.The diagram below shows a child on a swing. The child is swinging back and forth between points X and Z, through point Y. Points X and Z are at the same height. Which of the following statements best describes the kinetic energy and the gravitational potential energy of the child?
A.The child has no potential energy and no kinetic energy at position X and position Y.
B.The child has the same kinetic energy and potential energy at position X and position Y.
C.The child has more potential energy and less kinetic energy at position X than at position Y.
D.The child has more kinetic energy and less potential energy at position X than at position Y.
7.Deepak was performing an experiment in which he took a bottle of coke and Mentos. He poured some Mentos into the bottle and he observed a huge fountain coming out from the bottle. What could be the best explanation for such nucleation of coke?
A.Mentosare heavy enough to sink, they react with the soda all the way to the bottom.
B.Sugar in the Mentos reacts with carbonized drink
C.Because of rough surface of the Mentos that activates the carbonized molecules to come out from the bottle.
D.Because mint in the Mentos reacts with the CO2 present in the coke which nucleates it to come out from the bottle.
8.John is assembling a Quadcopter Drone, for which he require few components like Flight Controller, ESC(Electronic Speed Controller), Motors, Propellers, Batteries etc.Which type of Motor he should select for the drone for better speed and stability?
A.AC brushless motors-: They use induction of a rotating magnetic field, generated in the stator, to turn both the stator and rotor at a synchronous rate. They rely on permanent electromagnets to operate.
B.DC brushed motor-: brush orientation on the stator determines current flow. In some models, the brush’s orientation relative to the rotor bar segments is decisive instead. The commutator is especially important in any DC brushed motor design.
C.DC brushless motors -: developed to achieve higher performance in a smaller space. An embedded controller is used to facilitate operation in the absence of a slip ring or commutator.
D.Linear Motors-: These electric motors feature an unrolled stator and motor, producing linear force along the device’s length
