Answer:
The load weight is 2.29 N
Step-by-step explanation:
We note that at equilibrium, the sum of the moment and the sum of forces about a point is zero, therefore, we have;
∑M =0
∑F = 0
The parameters given are;
The distance of the load from the hinge = 35 cm
The distance of the load from the spring balance = 15 cm
The applied force on the spring balance = 4 N↑
The direction of the applied force on the spring balance = Upwards
Let the weight of the load = W↓
The direction of the weight of the load = Downwards
We use downward negative and upward positive coefficients for the forces
We take moment about the hinge as follows;
Sum of moments equals zero gives;
4 × (35 - 15) - W × 35 = 0
∴ 4 × (35 - 15) = W × 35
4 × 20 = W × 35
W = 4 × 20/35 = 2.29 N
The weight of the load = 2.29 N.
Answer:
Kay sold 67 cell phones and Allen sold 50 cell phones.
Step-by-step explanation:
Let k = # cell phones Kay sold and a = # cell phones Allen sold.
k + a = 117
k = 17 + a
So:
(17 + a) + a = 117
2a = 100
a = 50
Plug this back into 2nd equation:
k = 17 + a
k = 17 + 50
k = 67
Kay sold 67 cell phones and Allen sold 50 cell phones.
A. Fish man, goron, smith, other
B.98 people voted for goron, explanation 28 times 10 would equal 280 which is the number of people who voted, so every 10% percent would be 28 people
C, no 40 people is not correct multiple 40 times 10 and it’s 400 which is over the amount of people who voted
