Answer:
V = 27.46 m/s
Explanation:
given,
mass of the deer(m) = 135 Kg
speed of the deer (u) = 10.5 m/s
assuming,
mass of the car(M) = 900 Kg
initial velocity of car (v) = 30 m/s
using conservation of momentum
m u + M v = (M + m )V
V is the velocity of the car as deer is on the car
135 x 10.5 + 900 x 30 = (900 + 135 ) V
28417.5 = 1035 V
V = 27.46 m/s
so, the velocity of car is equal to V = 27.46 m/s
Answer
Structural psychology was first described by Tichener. He was student of wilhelm Wundt. Wilhelm wundt was the first person who has established psycholoogical laboratory. In this laboratory structuralist approach of psychology was used. Structuralism is supposed to be first formal theory in psychology. Structuralism separated psychology from biology and philosophy into its own discipline.structuralist method suggested that psychology is purely theoretical.
William James was a scientist who has established a laboratory in which Functionalism approach is used. Functionalism was not accepted in America. Functionalism was a reaction to structuralism. William James was not satisfied with structuralism and then he proposed Functionalist method. William James suggested that psychology should be practical instead of theoretical as was proposed in the structuralist method. He also suggested that the existence of consciousness and mind has a particular purpose, which should be the focus of the study.
Answer:
infrared waves
radio waves
ultraviolet waves
Explanation:
Radio waves are used for communication such as television and radio.
Infrared light is used by electrical heaters, cookers for cooking food, and by infrared cameras which detect people in the dark.
Ultraviolet radiation can kill bacteria that are present in water - this sterilises the water and makes it safe to drink.
Answer:
To determine the mystery component we will connect the mystery component to a DC voltage source, then I will measure the resistance of the component with the use of Ohmmeter, the value of the resistance of the mystery component will determine what the mystery component is
if the resistance > 1( very high ) then component is a capacitor
if the resistance = 0 then component is an inductor

Answer:
Explanation:
As we know that sound level is given as
so here we have
now we can take anti log both sides
so we have
so above is the expression for the intensity of sound in terms of reference intensity and sound level
