Answer: D (sandy clay loam)
Explanation:
It is because it is 55 percent sand, and 25 percent clay, so it has to be more sandy than silty. Much of it is by sand, so it is sandy. Loam is a fertile soil of clay and sand, so it is D.
Answer:
F is non-conservative.
If F were conservative no work would be done in moving back to the original point. F dot S = W if the net distance is zero the work done is zero for a conservative force
Answer:Correct answer: 15.85 kg·m/s
Explanation:
A 30 kg gun is standing on a frictionless sur-face. The gun fires a 50 g bullet with a muzzlevelocity of 317 m/s.The positive direction is that of the bullet.Calculate the momentum of the bullet im-mediately after the gun was fired.
Answer:
the answer is d
Explanation:
the more mass there is, the larger the gravitational pull is.
Answer:
a. 2N
b. 12N
c. 20N
Explanation:
Dtaa given,
Weight of rock in air=10N
weight of rock in water =8N
a. When the rock is suspend in water, it will displace some water from thr container since Buoyant force is the acts upward and equals in magnitude to the volume of water displays,
The buoyant force is calculated as 10N-8N=2N
b. The scale reading will be the sum of the buoyant force and the weight of the container
scale reading =10N+2N=12N
c. When the rock rest at the bottom of the container, the weight of the rock(10N) is acting downward and the weight of the container also is acting downward. Hence the sum of the two weight gives the reading on the scale
scale reading=10N+10N=20N
