Sodium (Na) is a Alkali metal so that's the answer
Answer:
the weight is 49.1 N
Explanation:
The computation of the weight is shown below:
As we know that
= 5kg of potatoes × gravitational acceleration
= 5kg of potatoes × 9.82 m/s
= 49.1 N
Hence, the weight is 49.1 N
We simply applied the above formula in order to determine the weight
Answer:
hello your question lacks some data and required diagram
G = 77 GPa, т all = 80 MPa
answer : required diameter = 252.65 * 10-^3 m
Explanation:
Given data :
force ( P ) = 660 -N force
displacement = 15 mm
G = 77 GPa
т all = 80 MPa
i) Determine the required diameter of shaft BC
considering the vertical displacement ( looking at handle DC from free body diagram )
D' = 0.3 sin∅ , where D = 0.015
hence ∅ = 2.8659°
calculate the torque acting at angle ∅ of CD on the shaft BC
Torque = 660 * 0.3 cos∅
= 660 * 0.3 * cos 2.8659 = 198 * -0.9622 = 190.5156 N
hello attached is the remaining part of the solution
Answer:
the vertical position is 1.1971m
Explanation:
Recall that

recall that 

this implies that distance = 12 * 5.0
= 60
therefore;
y = 1.1971m
the
9.3 x 10⁻⁶N
Explanation:
Given parameters:
Mass 1 = 70kg
Mass 2 = 2000kg
distance = 1m
Unknown:
force between them =
Solution:
The force between the two masses will be a gravitational force of attraction.
F = 
G is universal gravitation constant = 6.67430×10−¹¹ N⋅m²/kg²
r is the distance between the two masses
Substituting the parameters:
F =
= 9.3 x 10⁻⁶N
