A house is lifted from its foundations onto a truck for relocation. The house is pulled upward by a net force of 2850 N. This fo
Gwar [14]

Answer:

m = 95000 kg

Explanation:

Given that,

Net force acting on the house, F = 2850 N

Initial speed, u = 0

Final speed, v = 15 cm/s = 0.15 m/s

We need to find the mass of the house. Let the mass be m. We know that the net force is given by :

F = ma

Where

a is the acceleration of the house.

So,

F=m\dfrac{v-u}{t}\\\\m=\dfrac{Ft}{(v-u)}\\\\m=\dfrac{2850\times 5}{(0.15-0)}\\\\m=95000\ kg

So, the mass of the house is equal to 95000 kg.

Which feature is located nearest a continent
mafiozo [28]
The submarine canyon is the feature located nearest the continent. The Submarine canyon is any class of narrow steep-sided valley that cuts into the continental slope and continental rises of the oceans, it is sometimes extending well into the continental shelf, have a nearly vertical walls, and occasionally have a canyon wall heights of up to 5km, from canyon floor to the canyon rim, as with the Great Bahama Canyon. A submarine canyon originates either on the continental shelf or within the continental slopes. The submarine canyon is the main pathways by which the material such as stones and sand reach the deep sea.
