b) Michelangelo - 1475-1564
c) Raphael – 1483 -1520
Answer:
The correct answer is option B, High Renaissance
Explanation:
Given :
Vector A has a magnitude of 63 units and points west, while vector B has the same magnitude and points due south.
To Find :
The magnitude and direction of
a) A + B .
b) A - B.
Solution :
Let , direction in north is given by +j and east is given by +i .
So , and
Now , A + B is given by :
Direction of A+B is 45° north of west .
Also , for A-B :
Direction of A-B is 45° south of west .
( When two vector of same magnitude which are perpendicular to each other are added or subtracted the resultant is always 45° from each of them)
Hence , this is the required solution .
Answer:
The Supreme Court decision in Marbury v. Madison established the principle of judicial review. This means that the Supreme Court has the power to declare laws or actions of the executive and legislative branches unconstitutional if they violate the Constitution. The decision was made in 1803 and is considered a landmark case in American law and politics. It established the idea that the judiciary is a coequal branch of government and has the responsibility to interpret the Constitution and ensure that the other branches of government do not exceed their constitutional authority.
Explanation:
B. 3.2s
C. 0.32s
D. 2.1s
The power of an object is the rate of work done or energy. Here, the energy used by the hair dryer is 72000 Joules. Hence, the power used by the dryer is 1200 watt.
The power of an object is a physical quantity that, measures the rate of the work done by the object or the energy used by the object. The energy used is equal to the work done by it. Hence both have the same standard unit of joule.
Power is the work done or energy divided by time. Hence, the unit of power is J/s which is equivalent to watt.
hence power = work done or energy / time
Given the energy used by the hair dryer = 72000 Joules
time = 60 seconds.
then, power = 72000 J/60 s = 1200 watt.
Therefore, the power used by the dryer is 1200 watt.
