Since there are no choices, then this question calls for open-ended answers. Facts-based science must have proven underlying laws that support inferences such as Coulomb's Law, Kinetic Theory of Matter and many more. On the other hand, examples of science that focus on personal belief is philosophy. This depends on the perspective of known philosophers. An example would be Sigmund Freud who proposed the theory of 3 personalities. Although it is more on personal beliefs, this is used as a foundation in the study of psychology.
Answer:
θ=142.9°
Explanation:
d=1 *r
angle ϕ= 37.1°
the line connecting pebble and target should be tangent to a circle so
cos(180-ϕ-θ)=
=
∴ θ=180-ϕ-
θ= 180-37.1-0
θ=142.9°
Answer:
Explanation:
Force = (mass) · (acceleration)
= (1,000 kg) · (9.8 m/s²)
= 9,800 newtons
Answer:
230.53°
Explanation:
α = angle in rad / t^2
t =2mins = 2 × 60 = 120sec.
α = angle in rad / 2^2
α = angle in rad / 16
15+4(2) = angle in rad /4
23 = angle/4
23× 4 = angle in radian
92 = angle in radian
But π rad = 180°
1 rad = 180 /π
Therefore
92 rad = 92 ×180/π = 5270.53°
This value is far more so we subtract from 360° continuously till we get a value less than 360°
5270.53- (360×14) =5270.53- 5040
230.53°
Answer:
-0.375 m/s2
Explanation:
To find the acceleration due to gravity in this planet, we can use the Torricelli formula of UALM (uniformly accelerated linear motion):
V^2 = Vo^2 + 2*a*S
Where V is the final velocity, Vo is the inicial velocity, a is the acceleration and S is the total displacement.
With V = 3, Vo = 0 and S = -12, we have:
3^2 = 0^2 - 2*a*12
24a = -9
a = -9/24 = -0.375 m/s2
