Explanation:
Newton's second law:
∑F = ma
277 N − 245 N = (25 kg) a
a = 1.28 m/s²
Answer:
245N
Explanation:
We just need to multiply the force the man pulls the wagon by the cosine of the angle with the ground.
F = 330N * cos(42°) = 245.2N
To produce a single sugar molecule a plant must use a molecule of water (H2O) and carbon dioxide (CO2) and sunlight. To get 4 molecules, you simple use 4 molecules of water and 4 molecules of carbon dioxide.
No problem! :D
Answer: hey here's your answer...
Explanation: We can think of a force as a push on a surface, such as the force due to gravity you exert when standing on a bathroom scale. Pressure involves the distribution of force. The scale measures force, not pressure, so your weight reading is the same no matter how you distribute your weight on the scale.
Hope this helps...
Have a nice day-
Answer: 5.2427 x 
Explanation: To write a number in scientific notation, first write a decimal point in the number so there is only 1 digit to the left of the decimal point.
So here, we have 5.2427 and notice that there is only 1 digit to the left of the decimal point. Next, we count the number of places the decimal point would need to move to get back to the original number 52,427.
Since we would need to move the decimal point 4 places to the right, we have an exponent of positive 4.
Now, Scientific notation is always expressed as a number times a power of 10. So in this case we have 5.2427 x
.
So 52,427 can be written in scientific notation as 5.2427 x
.
