Answer:
C) 1200 rpm
Explanation:
= Diameter of bigger pulley = 24 inch
= Diameter of smaller pulley = 8 inch
= Speed of bigger pulley = 400 rpm
= Speed of smaller pulley
The relation between revolutions per minute and diameter is that they are inversely proportional.
The number of revolutions per minute of the smaller pulley is 1200 rpm
C. Establishing a seed bank with a variety of seeds of
different crop species
Explanation:
Establishing a seed bank with a variety of seeds of different crop species is a cooperative behavior that would best enable humans to prevent the problem of loss of biodiversity of cultivated crops.
- Modern agricultural practices is profit driven and centered on mono-cropping.
- Mono-cropping is an agricultural practice in which only one crop type is cultivated on a mechanized scale.
- Mono-cropping leads to less diversity of crop species as just only the cultivation of economically important crops are encouraged.
- In order to avert the menace that comes along with mono-cropping, seed banks are viable place to keep and protect other plant species from going into extinction.
- Seed banks provides a preservation of different plant species by focusing on storing their viable seeds.

Answer:
B) 0.493
Explanation:
First Crate
Formula: F=ma
120kg*1.05m/s^2= 126N
Second Crate
Formula: F=ma
3*120kg=360kg
360kg*0.71m/s^2=255.6
Find the ratio by dividing
120kg/255.6kg=0.4929
Round 0.4929=0.493
Hope this Helps!!
