Answer:
Explanation:
The friction force acting on the body depends on the mass of the body, here the mas of truck is very large as compared to the car, so the friction force acting on the truck is large then the car. So, the amount of heat generated by the truck is more than the car and the truck overheated more.
Answer and Explanation :
The opposition of the flow of alternating current produced by a magnetic field is called inductive reactance it is denoted by
, The value of the inductive reactance depends on the value of inductance. The good thing about inductive reactance is that it is not responsible for the power loss as resistance is responsible for the power loss
Answer:
D. independent; dependent
Explanation:
The dependent variable is the variable that is being measured during the course of an experiment. It represents the variable that changes with the manipulation of other variables.
The independent variables are variables which are varied or manipulated during the course of an experiment. The effects of their variations are measured on the dependent variable.
<em>In this case, the interval between the bell and presentation of food was varied and the effects of the variation was measured by determining the amount of salivation.</em>
Hence, the interval is the independent variable and the amount of salivation is the dependent variable.
The correct option is D.
Answer:
A compass works by detecting and responding to the Earth's natural magnetic fields. The Earth has an iron core that is part liquid and part solid crystal, due to gravitational pressure. It is believed that movement in the liquid outer core is what produces the Earth's magnetic field.
