Answer:
Explanation:
A)
vf² = vi² + 2(a)(d)
(54 m/s)² = (27 m/s)² + 2(a)(120 m)
a = 9.1125 m/s²
a = 9.1 m/s²
B)
d = (vi)(t) + (1/2)(a)(t²)
150 m = 0 + (1/2)(9.1125)(t²)
t = 5.7 s
C)
vf = vi + (a)(t)
27 m/s = 0 + (9.1125)(t)
t = 3.0 s
D)
d = (vi)(t) + (1/2)(a)(t²)
d = 0 + (1/2)(9.1125)(2.96²)
d = 40 m
The accurate about the planet’s climate system is the wind
because heating near the equator blows the wind to drive the convection cells in the atmosphere, and the friction created by the rotation of the spherical planet in the atmosphere causes the wind to appear to bend left or right across the surface of the planet. ..
The climate system is a highly complex global system consisting of five major components: the atmosphere, the ocean, the cryosphere (cryosphere), the land surface, the biosphere, and the interactions between them.
Solar energy drives the climate by heating the surface of the earth unevenly. Ice also reflects incoming sunlight, further cooling the poles. Temperature differences move the ocean and atmosphere as they work together to disperse heat throughout the globe.

A baryon is a particle consisting of three quarks or three antiquarks.
In order to form a neutral baryon (such as the neutron, which has electric charge zero), we must have two quarks with charge
(down, strange or bottom quark), and one quark with charge
(up, charm or top quark), so that the total charge will be zero:
A second possibility is to have a neutral baryon consisting of three antiquarks, of which two of them have charges
(anti-down, anti-strange or anti-bottom), and one of them has charge
(anti-up, anti-charm or anti-top), so that the total charge is still zero:
Answer:
F = 35651 [N]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of forces is equal to the product of mass by acceleration.
But first, we must use the following equation of kinematics to find acceleration.
where:
Vf = final velocity = 185 [m/s]
Vi = initial velocity = 0 (the cannon ball is at rest in the first moment)
a = acceleration [m/s²]
x = distance = 3.6 [m]
Now replacing these values into the equation:
(185)² = 0² + (2*a*3.6)
34225 = 7.2*a
a = 34225/7.2
a = 4753.5 [m/s²]
Now using Newton's second law we have:
F = m*a
where:
F = force [N]
m = mass = 7.5 [kg]
F = 7.5*4753.5
F = 35651 [N]
A material you are testing conducts electricity but cannot be pulled into wires. It is most likely a metalloid. Hope this helps!
