Explanation:
Hey there!!
Let's simply work with it.
Here,
load = 1200N
Effort = 200N
Load distance = 15cm
We have,
According to the principle of lever.
L×LD = E×ED.
1200×15 = 200× ED.
18000 = 200ED.
Therefore, Effort Distance = 90cm.

Answer:
a = 6.31 m/s²
Explanation:
a) The acceleration of the car can be found using the Newton's second law:
<u>Where:</u>
F: is the net force acting on the car
m: is the mass
a: is the acceleration of the car
W: is the weight of the car
θ: is the angle = 40.0°
g: is the gravity = 9.81 m/s²
Hence, the acceleration is:
Therefore, the acceleration of the car is 6.31 m/s².
I hope it helps you!
Answer:
(A) Like all objects, the Sun emits thermal radiation with a spectrum that depends on its temperature, and the Sun's surface temperature is just right for emitting mostly visible light.
Explanation:
The temperature of an object is a direct measurement of the energy of motion that absorbs all of the radiation that it receives (that is, it does not reflect any light, nor but many objects (stars included) behave approximately like blackbodies. Therefore, based on the location or the composition of the object, such as the Sun, it emits a spectrum of visible light
