Answer:
d = 186.3 m
Explanation:
Given that,
Speed of Matthew 3.45 m/s due eastward
It takes 54 seconds to walk to the store.
We need to find the distance covered. The product of speed and time is equal to the distance covered.
d = vt
Putting all values,
d = 3.45 m/s × 54 s
d = 186.3 m
Hence, he will cover a distance of 186.3 m.
The electric field generated by a proton is a radial field, so we would see the field lines going radially from the proton toward every direction. I've attached a picture representing the electric field generated by a positive charge, such as a proton, and we can see the field lines going radially from the charge toward every direction.
<span>240,000 miles / hour²
Average acceleration can be calculated by dividing the change in speed by the elapsed time. Since the dragster's speed was 0 when the light turned green, the change in speed is simply 300 mph. Now, divide that by the time:
300 mph / 0.00125 hours = 240,000 miles / hour²
By the way, 0.00125 hours is just 4.5 seconds!</span>
Answer:
Explanation:
Mass of gold deposited = 0.5 g
Molar mass of gold = 197 g/mol
Time, t = 6 hours
= 6 × 3600
= 12600 s
Number of moles = mass/molar mass
= 0.5/197
= 0.00254 mole
Assuming
Au --> Au+ + e-
Faraday constant = 9.65 x 104 C mol-1
Q = 96500 × 0.00254
= 244.924 C
Q = I × t
I = 244.924/12600
= 0.011 A
= 11.34 mA.
Answer:
Answer: B. Explanation: For an object to accelerate the force on it must be increased. According to Newton's second law of motion.
