I assume you mean planets eitherway interstellar dust and clouds have solid material and as well as minerals such as iron and over time solid chuncks start to fuse together and make a planet but with stars however it is different because a star has a little solid core surrounded by gasses (hydrogen and helium) to produce heat in a method called nuclear fusion so interstellar clouds contain gasses as well and solids as I previously said and form a star as well
this is from my understanding
Answer:
∆ = 14°
Explanation:
Let the angle be ∆
Opposite = 2.07 m/s
Adjacent = 8.3 m/s
Tan ∆ = opposite / adjacent
Tan ∆ = 2.07 / 8.3
Tan ∆ = 0.2494
∆ = ArcTan (0.2494)
∆ = 14°
The angle from vertical the raindrops make for a person jogging is 14°
Answer:
t = 6.63 s
Explanation:
Given that,
Initial velocity of the puck, u = 7.3 m/s
Deacceleration of the puck, a = -1.1 m/s²
Distance traveled, d = 5 m
We need to find the time the goalie have to stop the puck. Using equation of motion.
v = u +at
v = 0 (stops)
So,
So, the required time is 6.63 seconds.
a = acceleration of the bank cart = 4 m/s²
m = mass of the bank cart = 8000 kg
F = net force on the cart
According to newton's second law , Net force is the product of mass of the object and the acceleration of the object.
Net force = mass x net acceleration
hence Net force acting on the cart is given as
F = ma
F = 8000 x 4
F = 32000 N
hence the net force acting on the cart comes out to be 32000 N
