Sebuah mobil ditarik pada kecepatan konstan pada jalan miring menggunaksn tali baja pada C. Mobil mempunyai massa 1800kg dan pusat massanya pada G ( percepatan gravitasi 9,81 m/s² ) Roda bebas menggelinding sehingga rolling resistance diabaikan. Tentukan besar gaya T pada tali baja penarik pada C dan gaya reaksi pada roda depan dan belakang!

How does an observation about an object differ from an inference about that object

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
