Answer:
initial magnitude will be 9 N and direction will be to the right
Explanation:
force= 9N
mass m= 330 grams
acceleartion = a
from newtons 2nd law of motion we write
dP is the chage in momentum dt is time taken and F is the Force applied
this shows that the rate of change of momentum is 9 N
we also know that F= ma
putting values we get
a= 27.27 m/sec^2
The direction of acceleration will along the direction of force applied. So will be the direction of change momentum as in F=ma, mass is the scalar quantity and direction of force dictates the direction of motion. Hence, initial magnitude will be 9N and direction will be to the right
We Know: MA = d₁ / d₂
Here, d₁ = 4
d₂ = 10-4 = 6
Substitute their values into the expression:
MA = 4/6
MA = 2/3
So, Your Answer would be 2/3
Hope this helps!

Heat is transferred from the fire through the wire by conduction.
Explanation:
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.
