The net force acting on this object is 200N to the left. What is the force of friction and air resistance combined if the thrust force is 500N?
Answers
Answer:
Explanation:
Force of friction and air resistance acts against the external force . Let it be f .
net force = external force - frictional force and air resistance
Putting the given values
200 = 500 - f
f = 500 - 200 = 300 N .
Hence force of friction = 300 N .
How can a volcano develop in the middle of a tectonic plate?
Answers
Answer:
Volcanoes that form away from plate boundaries are created by hotspots. A hotspot is an area in the mantle that is believed to be somewhat hotter than the surrounding material. The rising magma from the hotspot can push its way through the crust and burst out at the surface, forming a volcano.
Explanation:
Volcanoes can form in subduction zones, which are regions where tectonic plates are interacting one and plate is sinking beneath the other.
Essay about how volcanoes form.A volcano is a hill or mountain in the shape of a cone that is erected around a fissure in the surface of the earth thru which heated gases, rock fragments, and lava are released. A conical mass grows around the conduit as the solid fragments gather there, becoming progressively larger until it reaches the size of a gigantic volcanic mountain.
Explain what a volcano is.A volcano is an aperture or vent through which magma, tephra (small rocks), or steam are released onto the the planet's surface. Days, weeks, or even years might pass between outbursts of volcanoes.

Balok diam diatas bidang miring pada sudut kemiringan 40° balok mulai bergerak,tentukan koefisien gesek statis antara balok dan bidang miring
Answers
Answer:
0.84
Explanation:
m = Massa balok
g = Percepatan gravitasi
[tex]\theta[/tex] = Sudut kemiringan
[tex]\mu[/tex] = Koefisien gesekan statik antara balok dan bidang miring
Gaya balok karena beratnya diberikan oleh
[tex]F=mg\sin\theta[/tex]
Gaya gesekan diberikan oleh
[tex]f=\mu mg\cos\theta[/tex]
Kondisi dimana balok mulai bergerak adalah ketika gaya balok akibat beratnya sama dengan gaya gesek pada balok.
[tex]mg\sin\theta=\mu mg\cos\theta\\\Rightarrow \mu=\dfrac{mg\sin\theta}{mg\cos\theta}\\\Rightarrow \mu=\tan\theta\\\Rightarrow \mu=\tan40^{\circ}\\\Rightarrow \mu=0.84[/tex]
Koefisien gesekan statik antara balok dan bidang miring adalah 0.84.
