Pressure is define as force per unit area. Mathematically expressed as,
P=F/A.
We are given, a mass of the ball equal to
m=1.6kg and an Area of 1.1cm2=1.1(
)m2
To calculate for the force exerted by the finger to the ball, it is simply equal to the weight of the ball. Mathematically,
F=W
Weight of the ball can be calculated as,
W= ma
where m=mass of the object and a is the acceleration due to gravity (9.8m/s).
Then, the Weight of the ball which is equalt to the force exerted by the finger,
W=F=(1.6 kg x 9.81)=15.696 N
Then Pressure would be,
P=(15.696N/1.1(.1(
)m2))
P=
142690.91 N/m2=142690.91 Pa
Answer: 2 sec means 1 sec each way
1522 m/s x 1 s = 1522 m
Explanation:
Can you explain a little more of your answer. I just wanna understand it more please and thank you:)
Answer:
1,056
Explanation:
mean tensile strengths is the sum of all the tensile strengths given divided by the number of tensile strengths given
Given tensile strength are 1037,1047,1066,1048,1059,1066,1073,1070,1040
mean tensile strengths = (1037 + 1047 + 1066 + 1048 + 1059 + 1066 + 1073 + 1070 + 1040)/9
= 9506/9
= 1,056.22
≈ 1,056
