The Sun's energy reaches the earth by Radiation
Heat is the energy transfer of an object with the environment or other objects because of the temperature difference between the two.
Heat moves from high-temperature objects to low-temperature objects
The process of heat transfer has 3 types
Energy from sun to earth through its atmosphere is not through conduction because the atmosphere is a bad conductor. Whereas convection is not possible because the earth must be heated first. And conduction and convection cannot pass through vacuum
Heat transfer from the sun occurs because its energy is carried in the form of electromagnetic waves
the type of heat transfer takes place when the furnace is up to an entire room
Convection is a mode of heat transfer
the sun transmits heat to Earth only by radiation
the process of convection
Keywords : heat, radiation, convection, conduction, sun
The first who discovered The Einstein Roses bridge it was discovered by Ludwig flamm in 1916 a few months after Schwarzschild published his solution and was rediscovered by Albert Einstein and his colleague Nathan Rosen which was published then in 1935
as stated in the other ans, wormhole or its scientific name, Einstein–Rosen bridge, was discovered by Ludwig Flamm in 1916. But note that Flamm's discovery was through a general relativity solution on black hole dimension by Schwarzschild. Both Schwarzschild's solution and Flamm's discovery are purely mathematical - no wormhole in reality has been found so far.
The force that must be applied to stop the SUV in 8 seconds is approximately 3,487.5 Newtons (N).
To calculate the force required to stop the SUV, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) times acceleration (a). In this case, the acceleration is the change in velocity over time.
First, let's find the acceleration (a):
Acceleration (a) = (final velocity - initial velocity) / time
a = (0 m/s - 18 m/s) / 8 s
a = -18 m/s / 8 s
a = -2.25 m/s²
The negative sign indicates that the SUV is decelerating or slowing down.
Now, we have the acceleration (-2.25 m/s²) and the mass of the SUV (1,550 kg). We can use Newton's second law to find the force:
Force (F) = mass (m) x acceleration (a)
F = 1,550 kg x (-2.25 m/s²)
F = -3,487.5 N

Answer:
294 J
Explanation:
To find the kinetic energy (KE) of a 3.00 kg toy falling from a height of 10.0 m, we'll use the kinetic energy formula: KE = 0.5 * m * v^2, where 'm' is the mass of the toy, and 'v' is its velocity.
We'll also apply the conservation of energy principle, which states that the total energy of an isolated system remains constant. This means that the gravitational potential energy (PE) of the toy at the initial height is equal to its kinetic energy just before hitting the ground.
The formula for gravitational potential energy is PE = m * g * h, where 'm' is the mass of the object, 'g' is the acceleration due to gravity, and 'h' is the height of the object.
So, we can equate these two expressions and solve for 'v':
0.5 * m * v^2 = m * g * h
v^2 = 2 * g * h
v = √(2 * g * h)
Plugging in the given values:
v = √(2 * 9.8 m/s² * 10.0 m)
v ≈ 14.0 m/s
Now that we have the velocity of the toy, we can calculate its kinetic energy using the KE formula:
KE = 0.5 * m * v^2
KE = 0.5 * 3.00 kg * (14.0 m/s)^2
KE ≈ 294 J
So, just before hitting the ground, the kinetic energy of the toy is approximately 294 joules.
