What is the slant of a line on a graph called "the slope." Slopes are in math, and science. Slopes look like slanted lines start from one side and to another.
Hope this helps!
Answer:
a) r = 4.22 10⁷ m, b) v = 3.07 10³ m / s and c) a = 0.224 m / s²
Explanation:
a) For this exercise we will use Newton's second law where acceleration is centripetal and force is gravitational force
F = m a
a = v² / r
F = G m M / r²
G m M / r² = m v² / r
G M / r = v²
The squared velocity is a scalar and this value is constant, so let's use the uniform motion relationships
v = d / t
As the orbit is circular the distance is the length of the circle in 24 h time
d = 2π r
t = 24 h (3600 s / 1 h) = 86400 s
Let's replace
G M / r = (2π r / t)²
G M = 4 π² r³ / t²
r = ∛(G M t² / (4π²)
r = ∛( 6.67 10⁻¹¹ 5.98 10²⁴ 86400² / (4π²)) = ∛( 75.4 10²¹)
r = 4.22 10⁷ m
b) the speed module is
v = √G M / r
v = √(6.67 10⁻¹¹ 5.98 10²⁴/ 4.22 10⁷
v = 3.07 10³ m / s
c) the acceleration is
a = G M / r²
a = 6.67 10⁻¹¹ 5.98 10²⁴ / (4.22 10⁷)²
a = 0.224 m / s²
Answer:
Explanation: It is inertia that causes the passengers to move toward the right side of the car. As the car swerves to left, passengers' body continues their motion as hitherto and as such it causes the passengers to move toward the right side of the car.
A). No. The medium is glass.
B). Yes. There is no material between the satellite and Earth,
only vacuum.
C). No squared. The rings are not electromagnetic waves, and
the material is water.
D). No squared. Sound is not an electromagnetic wave, and
the material is air.
