Answer:
Explanation:
When an amount of energy Q is supplied to a sample of substance of mass m, the temperature of the substance increases by according to the equation
where
is the specific heat capacity of the substance
In this problem, we have:
m = 55.0 g is the mass of the sample of silver
is the amount of energy supplied to the sample
is the change in temperature of the sample
Solving the equation for , we find the specific heat capacity of silver:
Answer:
The answer to the question is
The magnitude of the displacement needed to get the ball into the hole in just one putt is 1.746m in the direction of 23.41° north east
Explanation:
With trigonometric relation and the attached diagram we have
From the diagram the location of the hole is 3.32m- (1.57 cos45 +0.78co45)m North and
1.57sin 45 – 0.78 sin 45 meters west
1.658m north and
0.55m east
Thus the direction of the hole is 26.41 degrees
North east
The magbitude of the displacement is displacement is gotten from the relation diplacement of x and y =√(x²+y²)
∠26.41°
