Answer:
I only really know the "How do we use these EM waves in our lives?" part srry
Explanation:
EM waves are used to make sure you cellphone, radio, TV, and etc. have service/ connection.
Answer:
Explanation:
KE = ½mv² = ½(6.8)8² = 217.6 J
round as appropriate because that result is way too much precision for the inputs provided. Arguably should be 200 J based on the single significant digit of the velocity.
Answer: 225N to the right
Explanation:
The pedaling force is to the right and of 325N.
The air resistance is to the opposite side (in this case to the left) of 100N.
To find Net force of an object with two opposite forces acting on them then we have to subtract the smaller force from the bigger force and but the direction of the bigger force, so
325N-100N=225N
The greater force is towards the right proving the direction of the Net force is to the right.
Therefore the Net force is 225N to the right.
Please mark me brainliest.
In Euclidean geometry parallel lines never intersect. But in non-Euclidean geometry parallel lines can either curve away from each other, or curve towards each other. Example : the black lines that wrap themselves around the basketball.
Answer: B ) non-Euclidean
Answer:
Radiation moves out of the microwave into waves causing heat.
Explanation:
Inside your microwave oven, electrical energy is transformed into EM energy in the magnetron. When the microwave photons interact with food, food molecules are physically agitated, transforming the EM energy into kinetic energy, or energy of movement .
Hope it helped!
