Answer:
ABS
Explanation:
an Anti Lock Breaking system will not lock up your breaks even when used in a tight situation. This helps inexperienced drivers with no breaking technique break proprly.
Answer:
See explanation
Explanation:
The complete question is
Write a SELECT statement that returns the same result set as this SELECT statement, but don't use a
join. Instead, use a subquery in a WHERE clause that uses the IN keyword.
SELECT DISTINCT category_name
FROM categories c JOIN products p
ON c.category_id = p.category_id
ORDER BY category_name
The join clause gives us all the registers of both tables, for which the category_id of categories coincides to the category_id in the table products. That is, we can first select the distinct category_id's from products and the see the categories from categories table, whose id is in that list. That means writing the following query:
Select distinct category_name
from categories c
where c.category_id in (
select distinct p.category_id
from products p)
order by category_name
Answer:
safety glasses, hearing protection, respirator, work gloves, and work boots.

please give brainliest!! <3
Answer:
7 available
Explanation:
Since 3 colors are available r = 3
Total combination = 35
nCr = 35 ---1
nCr = n!/(n-r)!r!---2
We put equation 1 and 2 together
n-1)(n-2)(n-3)!/n-3)! = 35x 3!
We cancel out (n-3)!
(n-1)(n-2) = 210
7x6x5 = 210
nC3 = 35
7C3 = 35
So If there are 35 combinations, 7 colors are available.
Thank you!
Complete Question
Lumber jacks use cranes and giant tongs to hoist their goods into trucks for transport. Fortunately, smaller versions of these devises are available for weekend warriors who want to play with their chain saws. Let us model the illustrated tongs as a planar mechanism that carries a log of weight 210 N. Given the following dimensions: 35 mm 10 mm 40 mm 230 mm 85 mm 45 mm 10 mm 35 mm 345 mm determine the force in N and moment in Nm that our worker exerts on the tongs. Also determine the pinching force magnitude in N that the tongs exert on the log; i.e. determine the horizontal force that the tong's teeth exert on the log. Assume the point E is centered between the tong's teeth.
The diagram for this question is shown on the first uploaded image
Answer:
The force P is
and the moment M is 
The horizontal force that the tong teeth exerts is 
Explanation:
First let denote the dimension to corresponding to the diagram

Next looking at the diagram let us consider the vertical direction
At equilibrium

This mean that

Since they are acting in opposite direction the equation becomes

=>
=> 
At Equilibrium Moment about F gives

=> 
=> 
=> 
=> 
Here
is the horizontal force that the tong teeth exerts
Now let consider the part BAF of the system as shown on the second uploaded image
Now the angle
is mathematically given as

=> 


Now at equilibrium the moment about A is

=> 


=> 
=> 
=> 
Looking at the forces acting on the teeth as shown on the third uploaded image
At Equilibrium the moment about D is

=> 
=> 
=>
